The brake lights no longer work on my 63 Avanti. I checked the fuse, it looked fine but I replaced it with a new one. That did not solve the problem. So I ordered a brake light switch and went to install it and discovered that the threaded part is too small in diameter and does not fit or match the old part. I checked a couple different sources and they all give me the same part numbers and the same part as the one I already have in my hand. What’s going on? Is it possible? I have a non-standard master cylinder? I don’t think so. Here’s the new part that I have that does not fit.

Dave Thibeault is the ‘go to’ guy for a new throttle kicker…. They are not rebuildable .

It uses a special resistor, not the stock resistor. Also requires a new bracket for the resistor. The condenser is removed from the distributor. The stock coil is replaced with a Transigniter coil. The tachometer sending unit needs to be replaced. Did you try adjusting the plunger on the throttle kicker?

Thanks. I’ll measure the voltages to confirm. The transistorized ignition I plan to install it the factory option #196. It is not a full electronic ignition. To my original questions. Does the installation of the transistorized ignition eliminate the ignition resistor? If not, where can I order one? Can the throttle kicker be reconditioned/rebuilt? If not, where can I order one?

OK

Hello Dwight, let’s first wait for Jim’s reaction. / Thanks, Paul

Hi, Paul, For some unknown reason I never thought to look under the rubber boot. I have sent pictures of my second Avanti booster to Jim Lime and am waiting to hear back from him. The pix of the second booster are below. --Dwight

Pull the wire from the coil (the wire leading to the distributor) -- you don't want the engine running when doing this. The post on the coil which has the wire attached which leads from the ignition switch should have two wires attached. Put the ignition switch in the ON position and measure the voltage at this terminal. You may read 7-9 volts. If so, you probably have a resistor wire leading from the switch to the coil and would not need the ballast resistor. If you have full voltage, you probably have regular (non resistor) wire in place and may have a bad resistor, which you apparently suspect. (The wiring diagram shows an inline ballast resistor; my '66 has the resistor wire leading from the ignition and does not need the ballast.) A separate wire from the starter solenoid passes full voltage to the coil when the switch is in the START position. Have a helper hold the ignition switch in the START position; the voltage at this same terminal should now be 13 volts or so and revert to 7-9 volts when the key is released. If you have full voltage in the ON position without the ballast resistor in the line but the car won't run with the resistor in line, you may have a weak coil. If you don't know the condition of the ignition system, I'd probably replace ignition components, at least for now. Coils of that era are not designed to operate at full voltage.. As I understand it, the electronic ignition requires full battery voltage continuously; hence, you'd have to put in a relay to pass full voltage IF, IF you don't have full battery voltage with the ignition in the ON position which, again, would indicate resistor wire from the ignition switch. Welcome to the club. Come back here often. Lots of owners chiming in with tips, how to's, etc. Good luck and keep us informed.

As we start getting closer to the AOAI national meet at Palm Springs, I have 4 upgrades to do before then. The first was to figure out how to install a belly pan under the front end of the car. To start with, I ordered a factory Mustang plastic pan from CJ Pony Parts of California. When I initially laid it on the floor and looked up at the car, I could see why Avanti Motors had just taken it off when building the car and disposing it. The pan is fairly flat in design and the front lower panel of the Avanti curves upwards at both ends. However, once I put the car on stands and took a hard look at it, I figured out how to mount it. The back side of it has a couple of locator push in pins and 3 holes to place screws into the support. My 06 still had the screws in the support. The front side has some recesses, angled and straight, it form-fits around the A/C condenser base, radiator drain, etc. As it turns out, the front angled section, which at first seemed to be a real problem, became the mounting solution for the front since the angle Matches the Avanti lower piece fairly closely. Follow along with the photos and it should make sense:

New member, new owner. Recently purchased a 63 R2 automatic. Currently working on replacing most suspension components (bushings and shocks) rebuilding the power steering pump and hydraulic cylinder. After experiencing difficulties in starting the engine the ignition resistor was bypassed and it fired right up. My plan is to install the transistorized ignition, which I understand, bypasses/eliminates the resistor. I was unable to source a resistor. Thoughts on the above? Second issue was high idle. Current solution was removing the throttle kicker and plugging the vacuum hose. Idles perfectly now. Currently unable to source a kicker. Any ideas? Is the kicker serviceable? The action seems very stiff, IMO too stiff for the vacuum to operate properly, if at all. On a side note, there was initially considerable smoke, particularly from the drivers side which has now almost completely cleared since removing the kicker. My brother in law commented that he thought the smoke was fuel related rather than oil/piston ring related. I’m sure I’ll have a few more questions. Thanks in advance.

RQB3263/81/305 .... I just found a couple questions from October ?? the paint color is "diamond blue metallic ..original .... now thats the good news ..Suberu code 80 ...is a perfect match and no special mixing req... perrrfect been on there 10+ yrs now... the electric fan is 16" 12 volt off the shelf and is wired into the A/C compressor... on when a/c is on .... HAPPY HOLIDAYS EVERYONE FROM BILL IN SUNNY FLORIDA ...drive carefully and keep in touch

Hello Dwight, the pictures. Is there something you can undertake?

The story that has been told over the years, is that the California DMV established a new digital registration system around the time the 63's came out. The minimum number of characters accepted for a registration was eight. The Avantis only had seven ( 63Rnnnn), so the "A" or "B" was appended to make up the difference. The reasoning for one or the other, has never been revealed.... but someone knows... Nor is it known how far into the 60's that this process was continued. Any 64's with an A or a B... It was in mid 63 that the mandate to remove the 63 from the serial numbers was issued and to only use the Rnnnn. Any 63's or 64's with RnnnnAAA. Probably was a lot of sausage made in the DMV in those days.

I have seen B as well. maybe to distinguish 63 vs 64? I have R4551A, sold in Los Angeles.

We've been selling quite a few 2026 calendars in recent days.... get yours before they're gone. https://aoai.org/shop/2026-avanti-calendar/

Originally sold in California. Something about California requiring an extra digit or letter.

For those who know, what does the suffix "A" mean on a 1963 serial number, such as R-1234A?

It's been many years since I owned a '63 but I know that while the dash is out makes it the right time to do anything with the radio. I don't remember what size the front speaker is...whether it's a 5"x7" or a 4"x10" but either should be easily sourced. The bigger issue is making sure the speaker is of the proper impedance or the sound will be bad. With an original radio which is quite large compared to modern units the selection of speakers isn't good as a speaker with a larger magnet will not work as it won't fit against the top of the radio. There may be some decent speakers available today but you need to check the impedance and vertical dimensions for clearance.

Thank You regnalbob, That's awesome, Looking at the wire, I knew it had to be factory supplied and figured dealer installed. Only thing that made sense was that it was a bypass for the resistor, but I didn't want to take a chance. What I still don't understand is why it's so long. I wrapped many wraps around the harness. I guess what I can do is just run it along the harness and then wrap it and zip tie it under the shielding. Those service letters are fantastic. Thank you again
