Not sure what the present availability of 20 year old camaro/bird clips are in good shape, but the last time I wandered the junk yards, there are still a few around- or you could spring for $500 and get the whole car with a blown motor or tranny. I know of at least 3 decent looking birds within a 10 mile radius of home for sale in peoples yards.
If you are cash strapped and decent with a welder and torch, this is still a viable way to go. It does look ugly if you don't plan it and box it nice a pretty, even then it still doesn't look as clean as a stang design, but looks aside, the GM clips do handle well and don't need to cost a fortune - after futzing with it trading parts and buying new rotors/calipers, etc I think if you did it smart, you could be done for under $500 - $600 and two weekends of cutting and welding. The inner aprons lower edges will need to be trimmed and rolled to clear the A-Frames, you will have a nice cradle to set the V8 on and monstrous disk brakes and gobs of suspension as well as the ability to put a huge anti-sway bar on from a Formula 400 TA. Front radiator support shouldn't take more than 2-3 hours to do and if you do it right you can hang the front bumper brackets at the same time using the same structure. I managed to do this in a single weekend. Lots of naysayers were telling me I was ruining the truck and that it would never work . . . just the motivation I needed to get it done. I was into it for less than $300 and it aligned fine and drove great without any weirdness in tire wear or bump steer. Felt kinda floaty when in triple digits . . . but what 50 year old truck wouldn't at those speeds!
Personally, I am probably going to stick with a straight axel with monoleaf with the burb rod, 292 w/decent 200R auto and 4.11 gears. Put a dual master under the floor and see if I can rig the tranny shift linkage to a stock 3-on-the-tree shifter. With GMC oil guage and a set of decals - should look almost stock from where I'll be sitting.
