Are you asking about a C70 series Chevrolet medium duty truck?
The heaviest I've ever seen in a 70 is 8500lbs. They were quite common around here with either a 366 gas, 350 gas, or the occasional 427 high block truck engine.
replacing one that's twisted or broken? Used to straighten a lot of wracked frames in those trucks. Too light for dump work but farmers sure used and abused them.
It should be a ladder frame type assembly. They are strong is kept loaded envenly. It was the off center dumping that would put them down in a hurry. Sticking grain was a big contibutor to this. Being stuck in a field loaded and yanked out by a tractor was another.
If the steer axle width is not too wide for your application it will work fine.
If you could explain your project a little more I may be able to help you further.
I gather you want to use IH "R" line sheet metal on a GM later model frame, using a diesel engine and trans? Are you wanting to retain the 4X4 layout? I'm quite familiar with both series of trucks as I was repairing both types when in service regularly.

My 79 GMC 7000 (same as Chev C70) has a 9000 lb axle rating. Of course its been known to carry moreLOL. Came with diesel and now has a different diesel.

Nuthin wrong with a Detroit two cycle. I kinda like them myself with a set of ear plugs........
Both IH, and GM used a straight rail frame very near 34" outside diameter through the years. If you are planning to build an IH on a GM frame you will need to remove the cab and front sheet metal mounts from the original frame to install onto the donor, or cut and splice the frames together. You could also remove what you need from the GM and install onto the IH frame. I've not worked on a 4X4 setup on medium duty trucks much and assume this is a Napco, (sp) conversion? If you existing frame is in decent shape, it would be easier to locate a later model truck with the same spring perch spacing and just swap the steer axle.
I wouldn't use that trans however. An RT-910 Fuller is a 25% split evenly through all the gears and is both easy to shift, and very forgiving. It is an older transmission and therefore not expensive. The only drawback was a relatively fast, (for me) back up speed with a short trailer. With a straight truck, no problem.
