The Rangers are pretty narrow, I think they would work OK for something like an early '30s ride. The Dak was always bigger and would probably go better under mid 30s and up cars as they got bigger and bigger.

Here's the problem: It's much much easier to screw up a frame swap build, especially for a novice. So many things can go wrong.....quite a few of them end up unbuilt out behind the barn.

Unless it's one of those weird Knee-Action Chevies of the '30s, it's always better to keep the stock frame and suspension for the first rod or two that you build. Then when you have your wings you can try frame swaps. That's my opinion, old-fashioned as it may be.
