I appreciate the info. It's got a newly rebuilt 350 that's been bored 60 and it's pretty hot. I drove it for the first time today, so I'm pretty pumped about it. The rear end is stock, and geared too low to do any race car stunts (although I think I could tow all of the NASCAR equipment with it. Ha) I'll keep an eye out for a '71, and meanwhile adjust the drums to an adequate degree. I guess that means I'll be knocking on a lot more doors and asking "what do you want for that (insert rust-bearing object here) Thanks again
