Re: Rear end info -- 68 Shortbed

It sounds like you have your hands around it.

I'm assuming the 3-speed is a turbo 350 (maybe a 400). If so, 3.42s and that transmission is a good combo for what you want to do.

The bad news is that I've never seen a factory 3.42 on all the trucks we ever played with. 90% were 3.73s. Also, you're right - you'll need a different carrier for the 3.42s and the ability to set pinion depth, etc. if you decide to do it yourself.
