I bought what I thought was a late model FJ40 axle and stole the outers to do a disc swap on my 73 FJ40. I’m confused by the rotors. When I search this style rotor the closest thing I can find are rotors for an 85 mini truck. My question is, what’s the best rout to go to find discs and calipers that fit. The axle I bought did not have calipers. I was wondering what everyone else has done with this style knuckle. (See pics) I was assuming there were some better vented rotors that would fit but then the calipers that go with the rotors need to fit the knuckle. Any advice would be appreciated.
