I finally got my rotors and calipers for my disk brake conversion. I have all the parts from an 81' pickup and went with new rotors and calipers from a 92 4runner like i have heard many people doing because of the vented rotors and large 4 piston calipers. I was told anything from an IFS truck. Well the bolt pattern is not the same. Anybody know what really works? I have looked at all the tech stuff (which is where I got the idea). Thanks in advance.
