I got an old tube axle with my Bantam body, probably FLA Rod Shop. I was told it was for Ford spindles, but I have 1/4" vertical gap between spindle and axle (2" axle boss) and kingpin has 1/32" clearance in axle. Axle had a setscrew instead of locking pin. Spindle does appear to be horizontal on this axle. Do I just need to bush axle and get some shims?
