I've done a search regarding subframe questions and noticed that in most cases they focus on AD '47-55(1st) style trucks.

I have a 1946 1/2 ton that I want to do the usual open driveline, V8, IFS thing and will be using 15' Corvette Rally wheels.
Sticking a subframe in there will probably be the most cost effective way to accomplish this.
I have read differing opinions on the '79-ish Camaro subframe swap, most folks stating that it is wide and that a GM G body (80's Olds Cutlass, Buick Regal, Chevy Monte Carlo - ?) might be the answer (at least for AD series trucks).
Is this also the case for the 42-46? How different are the frames between the Art Deco series and the Advance Design series?
Also I may have the opportunity to grab an S10 frame from under a mail truck. Could I just graft the front of that onto my '46 frame? My understanding is that the rear of the mail truck frame is different from a S10 but the front is the same. If anyone knows the facts on this it would be great.
The truck is at a welder's shop - he will be doing the work as I don't have a place.

Gravity - It's not just a good idea, it's the law.
