Are you thinking of doing that with the crewcab cab? If so, what would it look like.
The main things that's pulled me toward the '62 GMC are sentiment, (first owner good friend), current title and tags, and year model is close to when motor was new ('64).
I measured the frame and wheel widths on the '79 yellow/black flatbed and the wheels and frame are about 9" narrower than a dually. I'm thinking now, I'd like the narrow set-up better.
I'm bouncing around like a ping-pong ball on what to mount the motor/tranny in, so all suggestions are appreciated.
I'm just now ready to start trying to find clutch/tranny/gear ratios that will match inter-state speeds and fit on the motor, which looks like it's not going to be easy. I'm learning these motors are pretty well a breed all their own.
If someone out there has some 3.21 (or close) gears they'd sell for a 14bolt chevy rear end, I'd sure be interested.
Thanks,
Cayoterun
