How about your front drive shaft? I think, I am going to have problems with mine. I don't have coil or shocks on right now, but I do have my radius arms, axle halves, and front drive shaft connected. When I let my suspension extend, my front drive shaft hits the transmission crossmember. There doesn't seem to be much clearance when the axle havles are level. Are the transmission crossmembers located differently depending on the transmission? Because I have a M-50D which is somewhat rare transmission in a Bronco.
