Mounted this assembly and hung my 37 Ford spindles only to find they bind on the axle drop area. Bought aftermarket spindles and arms and found the tie rod ends put the rods into contact with the bars. Had to convert to Heim joints.

What is the maximum frame width that will work with these wishbones. My frame is currently 35" wide. Do I need to narrow it? I'm also considering a 4 bar or hairpin setup. I will be using cross steering with a Vega Box. Thanks!
