is a '79 cab interchangeable to a '86 pickup?

[esnb74]

Hello all. I'm fairly new to this forum. Been lurking for some time as I look for a future pickup project.

Question: My nephew rolled my brother's 1986 1/2 ton 2wd last week while messing around with his friends. (Thankfully, the only thing hurt on my nephew was his ego). The '86 didn't fair as well: cab is toast, one bad fender, a fixable dent in the box.

My brother has a '79 sitting around with a decent cab. Will the '79 cab bolt onto the '86 frame? What about fenders? My bother likes the look of the '86 better - will the front clip on the '86 bolt up to the '79 cab?

I know these pick-ups are pretty similar, but we don't know how interchangeable they are? But, we were thinking this "may" be an inexpensive way to go.

Thanks for any help/advise!
