You made me curious and sure enough, no new sets. Hmmmmm. I wonder why? 3:36 is everywhere. And I have never even heard of 3:36. I had several 3:55 rears, a 3:08, and my '68 has 3:23 right now. That leaves scoring a new set on Fleabay, using used gears, or going with 3:36 or 3:08. That would depend on your engine and transmission combo as to whether either would make sense.

I only use GM HEI. But we put a Mallory Unilite on a friend's '55 Chevy. [not magnetic but rather an infra-red system] We kept blowing modules because the owner had NO grounds from the engine to the car. After adding three dedicated ground straps, no more issues. That Unilite is still going strong 20 years later.

It was not part of the 400 option. A manual rear antenna was the separate 381 option in '68. I believe the rear power antenna option was added in '69.

Thanks for letting us all know. Thats how we learn.

Motivated seller, make me a reasonable offer. Give yourself an early Christmas present, you deserve it!

I know this is an old thread but I would also like to know where to get that kickdown cable. The one my transmission guy installed won't snap into the square hole in my bracket. It's the same as that first picture.
Thanks

Still available?

Welcome on board

Welcome

You have the better gasoline back there. I used to run Sunoco 93 in everything. The junk we get here comes from the west coast. Total garbage that turns brown if you let it sin in a carburetor for any length of time.
The problems with the factory HEI distributors the advance slots wear after time and end up with way to much advance. The ignition modules also start dropping off over 4000 RPM.

63-74 GM cars, NOS, have 2 sets. $45 for both.

Original Saginaw power steering pump for 67-70 Pontiac cars, correct for A/C cars, but will work for non-A/C cars, just use smaller v-belt. Has original pulley, reservoir top and bracket and is ready to install. $325 shipped.

Pontiac Firebird 350 V8 and 350 HO auto Quadrajet, correct for 68 but will work on most 67-70 Pontiac cars. This carb has been in storage for 30+ years and has been cleaned and lightly restored with fresh seals/gasket set upgraded for today's fuel. Very rare carb. $900 shipped to you.

This may not be 100% original, but a good option. Manual disc master Rock Auto shows some 1.125" masters for front disc too. Front disc master No mention of power or manual in specs.
You know, back when these cars were new, it was SOP to rebuild master cylinders. I don't even know if rebuild kits are still available, but the FSM explains how to do it. You basically dismantle it, hone it out, and rebuild with new piston seals. You use alcohol to lube and clean everything.
