You should be able to score spindles, caliper mounts, calipers, rotors, grease caps etc. Spindles would be 70- e body, 73- a body, 74- F, M or J body. BTW, they need to be for disc brake not drum. If you have at least 15" wheels, then you can use the 11 3/4" rotors which give you more swept area/brake force. Always good to go for the max that will fit. Calipers and mounts would be for the same cars as the spindles. Larger rotors were on the cop cars and many other large bodied cars as there is a difference in them according to rotor size and caliper style.. Try to get them as a package so you are better insured it all matches up. Check out the the old Mopar Action tech article "Disc O Tech" I believe. Ehrenburg covers that quite well. The rotors you would probably want to get new, I would, calipers you could re-seal or get remans. Parts store stuff. If you get new rotors, get new bearings too. The rotors come with the races but no bearings. Don't put old bearings on new races. Get grease seals too. You for sure want the dust/spindle nut shields/caps as new ones are n/a and the a/m ones generally don't fit. Flex hoses you may need to look into a brake parts picture book if the ones for the disc application donor car are not going to work.
