The Corvette app is a rear trans type, I would suggest any of the others would be a better choice.

As for axles I'll tell you what I'm using in my 1-ton. Up front I'm using the IFS from. Chevy C20. I used a '72, but '71 to '87 are the same. This is the right choice for me but will result in a wide tall truck.

In the rear I'm using a GM 14-bolt on the stock springs.

I'm building a big motor trailer pulled and feel good about my choices. Something else may make sense for you, be sure to look at what Grigg has done. He and I usually end up in different places, but we usually know exactly why.


1955 1st GMC Suburban | 1954 GMC 250 trailer puller project | 1954 GMC 250 Hydra-Matic | 1954 Chevy 3100 . 1947 Chevy COE | and more...
It's true. I really don't do anything but browse the Internet looking for trouble...
