Price is certainly part of it.

When I was looking for one of those trucks a few years ago there were very few under about $4,000, which is a little much for a parts car in my book.

I think there are two more reasons.

First the front track width is pretty wide. You'd need to widen the fenders quite a bit to cover the front tires. The rear is quite wide too and would also cause some problems.

Second the motors are EFI on most of these trucks. That adds more complexity to any swap that uses the motor from the donor truck.

I bought an '89 K3500 (1-ton 4x4) which I use for pulling my car trailer or when there is snow on the ground like there is today. It's a good truck with an aging body and someday it may become a chassis donor for a project like this.

While my projects are mostly AD based, my thinking is that this chassis would make most sense under something newer. Maybe a '67 because I really like that body...

It's true. I really don't do anything but browse the Internet looking for trouble...
