Hi Brooks- I took the liberty to look RQB2594 on the Bob Johntsone Avanti Registry site. Has your new purchase been improved upon from the Photos taken way back in 2002?

Excellent solution- well done, MFG. 🫡 I suppose for those without Milling Machines, a series of holes might do, although hardy souls might elongate these with a round file.

Hi Brooks- The Tee is meant to be a fuel tank drain but it gets pretty negative reviews on that subject. I think it is an NPT pipe plug 1/4" ... Common NPT Pipe Plug Sizes: 1/8" NPT: The nominal size is 1/8 inch, but the actual outer diameter of the threads is approximately 0.405 inches. 1/4" NPT: The nominal size is 1/4 inch, with an outer diameter around 0.540 inches.

Geeze I wish I could buy em for barely twelve bucks each - here 'down under' I was pleased to buy a pair for &95 incl post.

Hi Brooks. If you have a Disc Drum system on your Avanti, you probably (read, ought to !) have a proportioning valve on it. I had a Kelsey Hayes valve on the inner Left hand Frame Rail down below the Mastetr Cyl location. I have replaced it with a GM PV2 Combination valve which has the same port configuration of the old KH unit and even bolts up exactly the same. I believe the bottom port of the Master Cyl will be for the Front Disc system. This line will go to the Combination valve as indicated in the screen shot posted- i.e. top, next to Brake sensor, at the end closest to the little rubber plunger cover. A shot of my Master cyl is also shown for your comparison. If you need further clarification please do ask.

I believe you will need to remove the original Rivets. These can be replaced with similar rivets if you trim the length so when assembled , you have only 1 x the diameter protruding. These can be gently mushroomed over with a hammer (buck the head end on a soiid flat steel surface) to secure the cover once again. Tinmen's or pan head rivets ought to do. You might even be able to use suitably sized flat head nails as substitute rivets (done that before). Pop rivets might do but use steel ones not Aluminium otherwise they might loosen up in service.

Thanks Ron- I will compare that carb number to the ones I see here in Oz and pick one up eventually. My 305 will likely require a re-jet smaller , I excpect.

Thanks MFG- I have recently fitted a dual exhaust (minus Cat- I'll take a risk.. ) whilst the body is off the Frame. The Carb and Distributor are up for substitution after I get the car reassembled and inspected for roadworthy. I'm looking for an Australian delivery carb that was jetted for the Holden 308 or Pontiac Parisiennes befor the late 70's.

Hi All- As an aside whilst this thread is open... I have a 1981 EME Carb that I'd like to replace with an un-ECU controlled Quadrajet someday. Would somebody mind putting up what Carb Code numbers might be a good idea for substitution. BTW if I do go down this route , the AIR Injection system and Catalytic converter will also be gone too. Charcoal Canister will be staying , however. Thanks...

Hi Klaus- I'm making a few assumptions here but having replaced the mountings for my 1981 305V8 recently, I'd wonder whether they might be the same because these engines are small block Chev. I used the same ones recommended for Corvettes 1969 to 82. I have engine mount 'pedestals' on my Front Crossmember as in the photo. If yours are the same, I'd look at the corvette mounts. By all means let me know if I'm wrong !

Thanks for the feedback everybody- Question for Ronmanfredi and Geoff.... How does the roof Headliner come off? I have no Idea how to remove that and I'm wary of spoiling it. 🤨 My Sunroof is already well corroded and I reckon it will need removal for any repair/restoration.

Geoff- I applaud your pioneering work and the photos help tremendously. I cannot help but think repairing my sunroof might be folly given I have extricated some really rusty metal pieces so far. In any case your pictures paint a very good picture of what is in store- thank you and keep 'em coming ! 👍

Update- I have managed to remove the outermost screw easily, however the innermost one is rotating without releasing. We have pushed wedges under the base of the bottle and rotated the screw in an attempt to raise it, but no go so far. I don't wish to resort to butchery so if this won't come out I think I'll have to very carefully grind off the head of the Screw using a finger belt grinder or similar. Going overseas for a month shortly so this might be a dead thread until I get back....

Thanks Grant- much appreciated... I had gotten under there but will be a bit more prepared for what to look for, next time.

Appropos 1981 Avanti II - Can somebody please provide some feedback about how to go about removing the windscreen washer reservoir/bottle. How is it attached? Repainting the engine bay soon so info is very appreciated. I'd hate to bust it. 😒
