'67 Cab & Bed on 84 Frame? Pro & Cons. - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I have all the parts and would like to know if there are any hidden surprises in store?

The frame/location of the front wheels are like 3" longer/farther forward than a 67-72. The core support needs to be moved back and the frame horns cut back. The frame rises up a couple inches more under the bed than 67-72s, so you'll need to raise the cab that much to have the bed line up.

Many thanks for the reply special-K. I'm glad I asked and got better information on the differences before going to all the trouble of removing the cab and finding the differences the hard way. Looks like I need to re-think my project and go back to the drawing board. Looking at the later frame I can see the rise in rear but didn't know there was that much difference. This also means I can't clip the rear of the later frame and add it to an earlier one without the same problem, which was Plan B.

The real question is "why the swap"?

I bought a junker '84 long wheel-base diesel truck and sold off the sheet metal because it was too rusty to save. In the deal, I got a 350 Smallblock and Turbo400. Before this I traded up a long wheelbase Fleetside '67, with a 250 three on the tree that is dead in the water. In between these deal I came up with a short wheelbase '67-'72 Stepside bed. I was going to shorten the newer diesel frame that is in primo shape because the engine went sour early on. My idea was to swap out the '67 cab and stepside bed for a 'go anywhere, almost' 2wheel drive truck and add a home-made aluminum slide-in camper (to keep the overall weight down), with 31" tall 15" all-terrain tires (depending on what's available and so on. The polar opposite of an 'in d' weeds' ride; more of a 'get the hell outta Dodge' type mojo without the headaches of a 4x4 in the middle of nowhere going sour, since this is not something I want to use off-trail. I haven't given up on this idea but don't want to re-invent the wheel, either. Maybe I'll just trade the front cross-member and use the later springs, after I shorten the frame. I have owned several trailing link trucks and they tend to sag with extra weight, even with air shocks. I'm even thinking of using a granny 4 speed behind the six banger as I have electronic ignition and a new set of headers for that. Economy, and the ability to burn crap gas is also high on my list as desirable aspects for this build. Something that sits up but does not have a high center of gravity like a Conestega wagon, but similar to thos in that I want to go places and see things without spending a fortune building it, or in maintaining it while on the road. This is not to say that I haven't already done the 'hot rod pickup' jango. I originally thought of that, but camping and hiking sure is fun when you have a place to stagger back in and crash without all the hassles of motels and the icky factor that goes with them. (I won't rant on that.)
