Hey guys, I'm working on a 57 Ford Custom gasser project and am curious exactly how beefy i need to go with the front frame rails and front cross tube. I've seen some guys use 2x4 and others user 2x3 for the frame rails I'm assuming about 1/8' thick or so?? Also what about bar across the front? Would this be same dimension as a roll bar 1 5/8 x .113? Or larger? Thanks for input.
