Comanche Frame Replacement

After searching multiple forums, i am seeking help with a few questions on my next build. I recently acquired an 89 Comanche for $300 off of a friend. The cab is in good shape, and the interior is half decent. It is a 4Cyl, 4Spd 2wd. I already have a parts XJ to swap the axles, and the powertrain and interior out of. The XJ is totaled, with no floor or unibody left unrotted.

The only problem is, the comanche has a shot frame. The unibody under the cab is pretty rotted from aout 3 inches behind the front control arm mounts, to the back of the cab, and the rear frame is completely rotted and has been cut off. I have a new complete rear frame assembly off of another parts truck to weld onto the 89 Cab. If i were to replace the unibody from the control arm mounts back with 1/8" or 1/4" C channel, and additional plating, then use a piece of square channel to reattach the rear frame assembly, and add additional plating on the outside, would it be strong enough to hold up to the stress of flexing out the truck, and carrying a truck full of gear?

I could really use some of your input on this project. I have the time to do it, i just want to know if its plausible. Will it hold up to the stress i will put on it? Or would i be better off scrapping the two jeeps, which i was trying to save firstoff, and cut my losses?

Any input would be appreciated, and any help or tips as well.

Thanks guys

Pictures would be extremely helpful in determining if this is worth doing or not. But from what it sounds like you may be better off parting everything out, scrapping whats left and then take the money you get and find your self another MJ.

My 2 cents

This is a small list of the Comanches for sale in Pennsylvania, I am not sure of your budget, these are 1700 and under. There are a ton more of them for sale these are just the ones that were reasonably priced.
