You also need caliper brackets from Speedway. The brackets can also be bought on eBay. The brackets need to be welded on the rear housing. Over all you can install rear disc brakes for around $200, IF you shop around for parts. Rockauto, and eBay seem to have the best prices. Jeff

From what I can tell the hat of the Jeep rotor is deeper then the Explorer rotor. That will change the location of the caliper, and where the mounting bracket is located. Jeff

Jeff well i guess i will wait and see which rotor you use.lol also i think you have a dana 60 in your car right? my car has a 8-3/4 with moser axles and green bearings. so i wonder if the measurements would be in the same place? probably not just asking. also what do you do about the backing plates for the drum breaks? i mean can you just pull them off and bolt the axle back to the axle housing?? sorry for all the questions.Bobby 3520 pound race ready 1973 Street/Strip Dodge Dart - Stock stroke 440/727 10.49 @ 125.0 on 93 pump gas & ET Street Radials.

Quote: http://www.oreillyauto.com/site/c/detail...5&ppt=C0066 looks like this might end up costing less that i thought. also if you go with the jeep rotors what year would use and last question what are you going to do for break lines for the back. i mean wear the line hooks up to the caliper. thanks for the help Jeff.
