Not sure where to start here. My name is Rick, I'm in Arizona, and I've been into Chevy trucks since 1986. I've got a '63 4x4, and several other '64, '65, '66 trucks, as well as an '88 Suburban. I know, I know, they're not K5's!
The reason I'm here is because I've been doing some research on an overdrive unit for hours, and the only reference I can find to it is on one of the forum threads here. It's a cast iron unit that mounts between the transmission and the bell housing. The problem is, it's used, 500 miles away, and not cheap. To top it off, the current owner has never used it himself, so info on how well it works, it's condition, etc, is non-existant.
Anyway, if anyone has any information on this thing, please let me know, I would really appreciate it. I posted a comment (my first post here) on the thread that mentioned this unit a few minutes ago. The last post was back in '05 though.
Thank you,
Rick
