Do you still sell these?

What he said. It needs pre-loaded to close the baffle. At room temp, it should be closed and the spring is what does it.

A couple of years ago I put my 67 back to the original configuration with a 67 rear end and the stock two traction bar setup. It had a 69 rear end when I got it. I really like it this way.

It seems like it should be 7645835, based on this page: https://www.teufert.net/partbook/67-76/10-p.pdf
Look under "10.266 Cylinder, instrument panel compartment lock".

I still prefer 4 wheel discs. I also tend to change to 4 wheel discs whenever possible just to avoid the torture of servicing drums. I can't think of a single vehicle that still has drum brakes. But what is worse is the 4 wheel disc set-ups that use a small drum brake inside the rear hat for a parking brake. Hard to service and a piss poor parking brake too. In that regard the second gen Firebird rear discs are the best to use.

yea
Have a look at the body bushings
