Relax Jeff,
no one is going to talk you into putting one under your 37. Besides it doesn't fit well under a 37. It's better suited for fat fendered pick ups, 46-52. No, the frames are not too big. They're almost the same size as the originals, except the frame rails are 3" by 5" boxed instead of 2" by 3" C. I spent months researching the swap. Why should I spend thousands of $$$ for independent front suspension, power steering, power brakes, front discs, plus all the accessories to hook it up. When I can get it on one frame for a couple of hundred $$$. Butcher the body??? The only cutting I'll do is to the opening in the back at the bottom of the cab, I'll extend the opening from 38" to 40". Then a few squeezes of the tin snips on the inner fenders and that it.

I do agree with you on one point...The best frame for any car/truck is the original...Sometimes some of us feel that the original is not good enough or we just want something different.
