I have often thought, while checking some builds, that by the time guys cut the front end off and weld in a different front clip from some other old car, then cut the rear off to install an aftermarket or home made c notch, then boxed the rest of the frame, the only part of the frame they actually re-used is the center section under the cab. they might as well have spent the time on building a frame jig and built their own. that way the old car front clip could be properly installed to a frame made the correct width and height to match the "new" clip and the rear section could be made to match the suspension and frame width required back there.
just my thoughts though.

When I was trimming my frame rails for the MII crossmember, I was thinking, "Boy, some smooth frame rails would be nice..."
For the reasons you just stated, is why I've never thought the chassis swaps with late model trucks were viable. By the by the time the chassis is lengthened or shortened, chopped and C notched, crossmembers added or removed, not to mention what it takes to mount the body to the frame...
Anyhow... starting with a chassis made for your truck seems to be a whole lot better option. Even starting with some 2x6 tubing and doing yourself seems to be a much better alternative.
OK, I'm off my high horse now.
