I've decided to make an attempt at "tightening up" an original shifter for my 66. This is the same shifter body that was used in Canadian Pontiacs, Beaumonts, Acadians, numerous Chevrolets and I think maybe some Buicks prior to 1967. I have it all disassembled and need to order some parts for it. Fo...

I figure I might try to document the conversion of the 65 Laurentian, from power glide to a 4 speed Muncie M20. I'll ad that Carl Stevenson has been a invaluable resource on this conversion, and has helped me out immensely. thanks Carl! And be sure to check out Dave's conversion post sticky as well. I'll...

It can be smooth when the bolts turn like new. Even the lines came undone. No rust. Drivers side needed the Vice Grip, but only just (because I wasn't willing to wait for the PB Blaster to work). But I'm sort of worried about the flex line to main chassis line. Cracked it open and pulled the axles. They hav...

I've thought it might of of interest to document my TH400 build, hopefully sparking some discussion around of what is best. Like my rear end build, the transmission was originally one of those things "Black art" and best thought as being left to the pro's. I have had very good success with my 12 bolt bui...

Not sure what the exact name is but looking for a 283 canister drop down cone. It goes inside the oil filter canister and seals the bottom of the filter. Filter doesn't do a thing without it! -- Edited by hawkeye5766 on Tuesday 6th of April 2021 01:31:26 AM

Is there a way to drill a hole in a hardened steel shift lever? In the picture you can see the lever on the right has a second hole closer to the pivot point to allow for "short stroke" shifter operation. If I am right, a normal drill bit would maybe scratch the surface of the left lever if I try to drill a hole i...

A while back there was a thread here on 67 and older shifters which included an eBay source for replacement parts. My 1968 Acadian / Nova Muncie shifter was prone to binding & locking up. After stripping it down it appears the 3-4 lever is the problem. The eBay seller lists his parts as 64 - 81 Corvett...

As most of you know I have a 66 Grande in my garage...but don't know much about them and am looking to get educated!!! A few questions on a SB Grande.
