On my 35, I built a new frame from 2x4 tubing, but I ran fenders all the way around. There are several frame manufacturers out there, all you need is a wheel base and a width close to what you want. I suspect nearly any brand in the mid 30s would work, Ford has the most aftermarket support. Its best to figure out what you want the car to look like (final style) before you make a decision on a frame as that can alter the options on the frame chosen. Gene
