I'm no help to you, but please let me know what you find. I'm facing the same thing with my 83's stupid "double gunsight" modified hood.
-
And of course the rear brake cylinders can be ordered from Studebaker International.
-
Are you saying that the handle broke, or that the hi-low won't change from one to the other?
If it's the latter, I had that happen on my 83 a couple of years ago. Fixed it by getting my head under the dash and fiddling with either the wires or a rod on the bottom or side of the steering column. Sorry, but I can't remember exactly what I did, but the fix didn't involve pulling the column apart.

That one has the blower mounted where my a/c compressor is. A prior owner had a Paxton SN/2000 installed on mine - on the passenger side (the alternator was moved to mount under the blower). The PO had a second "gunsight" grafted onto that passenget side of the hood. With a hole cut into the normal hood contour at the blower's highest point, the fairing gives the extra maybe 1" clearance that the blower needs. Of course, in my opinion, it also degrades the look of the car.
Don't know what the blower did for the 327 or 350 on the late-60's Avanti, but with the 305 mine came with, the blower at least provides decent performance. Without it, the 305's a slug.
Question: The carb bonnet on that car isn't the stude one. Any idea who makes or made it? I really want to get rid of the Paxton's airbox and replace the Holley with a sealed Edelbrock carb.

From the books that I have, it appears that the "standard" plug was the AC R43T. I've been using the R43TS projected nose plug in my small-block powered boats over the years and in my 83 Avanti. The projected nose design is supposedly somewhat less prone to detonation, otherwise exactly the same heat range and performance.

I just checked clearances on my 83 with the Dayton wire wheels and 7.15x15 tires. The tops of the tires are just barely below the fender oeping level. The widest part of the tires look like they'd hit the inside of the fender lip if a bump could drive them up that far. They've worked fine for me for the past 4 years and the original spare looks to be the same size. The major difference is that your 1963 model has the front of the body somewhere around 1 1/2" to 2" lower, with the front wheel cutouts that much higher than mine. That means that the fender is maybe a half inch to an inch narrower at the opening's top, and that may be enough to give a clearance problem.
You might offer the seller a fee plus shipping (probably he'll also want a signifcant deposit) to send you one rim to try out. That way you'd be able to make an informed decision. If it fits, fine. If it doesn't, you ship it back to him and he keeps the "try it" fee. The Avanti's an elegant design, not a hot rod, and to me it looks its best with wire wheels.

Before you do anything, get the shop manual. SI and others have it on CD for $20. The in-out adjustment is done with shims between the hinges and hinge mount panels. If adjusting using shims doesn't get you all the way there, then you can consider elongating holes.
-
Thanks, Ernie. 2 3/4 is what fits the SN2000's outlet, so that's perfect.
Apart from the sealing and vventing, the marine carb probably is jetted a bit richer than the auto version. that would be about it for differences. If I do decide to try this, I'll certainly take advantage of your experience.

What I currently have is an 83 Avanti with a Paxton SN2000 that blows into a Paxton air box containing a Holley.I asked the hose ID to see if either SI's Avanti R-2 blower-carb hose, or their flex hose for the Lark R-2 is the same ID as the SN2000 to air box takes. If the hose ID matches my blower outlet-air box intake fittings then one of these can replace what I have on there now.
Since SI also has a catalog listing for the 63-64 air bonnet, I got to thinking that it might be fun to replace the air box and Holley with the bonnet on an old AFB or a Marine Edelbrock with some kind of an air horn reducing adaptor. Or the old AFB top on an Edelbrock - I think I've read posts of someone doing that. I could call the setup a homebrew R-305. Anyway, that's why I'm asking for the dimensions.
-
What's the inner diameter of the R-2's blower to carb bonnet air hose? Is it 2 3/4"
What diameter air horn does the bonnet fit? Is it 4 1/8"?

78 Corvette wires work well. The Corvettes seems to have used the same exhaust manifolds from 1968 to at least 1978 and of course had the HEI distributor in 1978.
-
Yeah, they're Rams Horns manifolds though not as tall as some I've seen. And it's an HEI distributor, albeit the Canadian version. I'm assuming that a PO changed that from the US style computer controlled GM HEI when he re4placed the computer controlled Q-Jet with the current Holley mounted in a Paxton air box.
I'm still hoping to avoid having to fabricate a plug wire set. Question: what year did Chevy go to that distributor? If I know that, then it shouldn't be a big deal to find a set that'll work well.
-
I've replaced the PO's miserably done headers with 68 Vette exhaust manifolds (they look just like the one shown in the engine and chassis photo on page 45 of John Hull's "Avanti - The Complete Story". Can anybody tell me what kind of an ignition wire set I need to buy? I looked at a set for an 83 Camaro, and that won't work.
The garbage wires now in there are so bad that last night the steering bellcrank (Pitman arm?) hung on the wire to #7 when I made a left turn. Popped the connector off the plug, broke away from the distributor connector, dropped away and got hung on the power steering hoses where I found it this mroning.

3771 has one leaking rear brake cylinder. I got new cylinders for both rears from SI. Might as well have the brake shoes replaced, but don't know what to tell the mechanic to get. The only reference I've found is that "The rear brake shoes are a #228 for an 11"x2" drum. To tell the auto parts store it's a rear brake shoe for a 69 Chevy Caprice." Can anyone tell me if this is correct info, and if not, what shoes will fit?
-
My 83 (3771) has no holes.And doesn't overheat even though it has a blower adding to the normal Avanti engine heat.
-
My 83, #3771, did not have the circuit board you mentioned. Maybe it's an amp? You've checked the 10 amp radio-tape-cruise control fuse? It's the middle fuse in the lowest row that has three fuses side by side.
The radio in mine didn't work either. In my case it would produce nothing but faint static. Replaced it with a modern radio/CD player unit. I cut the stock radio faceplate opening larger to fit the new unit It looks better than the Avantis I've seen where the owner eliminated the Avanti's stock faceplate and used the faceplate surround piece that came with the radio.

Your question referred to a 63 Avanti. As I recall, the original Avantis were equipped with 40 amp alternators. But then you refer to an 83 Avanti. By 83, Avantis were equipped with Delcos that probably put out around 100 amps. I don't have specific data for 83.
Thanks, it is an 83. This weekend I may have to pull the supercharger off to replace the PO's garbage headers with 68 Corvette manifolds, so I'll look for a number then. (the alternator's mounted under the blower so I can't see squat of it now) I checked 82 and 83 Monte Carlos to see what they used on the 305's: 63 amp without a/c, 85 amp with. But that doesn't necessarily mean anything as Avanti then was buying what amounts to crate engines from GM.
-
What max amp rating alternator came on the 83 Avanti? Probably the same came on all Avanti II's post-1975, so info from one of those would be of use also. My 83 has had a bunch of electrical add-ons and the alternator on it can't quite keep up with the demand.
I've moved the voltmeter + feed to the radio/cruise control fuse which is a switched feed, so it's not the old clock circuit which Avanti Corp used to feed the voltemeter that's slowly draining my battery.

Collector or show car: Studebaker Avanti
Daily driver: Avanti II
Car to customize: Avanti II

On my 83, NAPA 7370 (lower hose) fits almost perfectly without any cutting. I did have to re-use the insternal spring from the old hose. My upper hose(s) begin with a sloppily cut slightly curved hose section from radiator to filler cap piece, then a "straight" ribbed hose from there to the engine.
-
Look closer - it's not at all similar.
-
Can anyone give me any ideas where to look for Avanti taillight housings? Mine are in pretty sad shape (chrome flaking off corroding pot metal).

Problem is, Lew, none of those people would have a clue who Ian Fleming was.

Can you post photos? What color is the interior? Automatic transmission?
Oil Pressure sender for 305
in 1965-83 Avanti
Posted
When I bought my 83, its oil pressure sender didn't work. I bought one for an 82 Camaro but it's not the right fit. First, it's slightly too high to fit properly under the edge of the distributor, and it reads low. It's better than nothing but it'd be nice to have one that fits and reads accurately. Do any of you have a part # for the sender?
