has anyone used FJ60 rotor and calipers for there rear disk break conversion on thier fj40?
I already have the rotors and caliper and was wanting to use them. I can weld and don't mind using a weld on kit or if you have a template I could use that would be great. thanks

Rotors will be next to impossible to use, on the front they are mounted outward facing surface against an inward facing machined surface, the inboard side of the rear axles is not a machined surface. You need to used a slip on rotor with both surfaces machined cause it's gonna be sandwiched tween the axle and the wheel
