i bought a disc brake conversion kit for my 37 ford axle. it will use volare rotors. i am not a mopar man, so i don't know of all the body styles that have the same rotor as the volare.i mean all of them that has the same bolt pattern,and same size bearings. fords i know,but i hate mopars,so i am ignorant about them. i guess i shouldn't say that,because i will probably catch a lot of shit. so nobody take offense.to each his own.ron.
I assume your question is "What rotors do I need to buy from the parts store?" I didn't see a question mark in there. There are two sizes, the small rotors that are 10.xxx" and the large rotors which are 11.xxx", i don't recall the exact sizes. The small ones are standard, the big ones are for cop cars and other heavy duty use. Your kit likely needs the small ones. 1976-1980 volare and aspen.
If the kit that you bought didn't have rotors with it, didn't the instructions tell you which one's to buy? Either by part number or size?
Check into the Rock Auto site. Their catalogue is pretty good and is easy to cross ref part numbers. You can take the Volare/Aspen part number, search for applications, and see what else fits. The phone service isn't too bad either. .
