Without the spindles this is the regular kit from wilwood for converting your front drum setup to disc. It includes the hubs and bearings, rotors, calipers, brake pads and all the hardware to mount them to the stock a-body drum spindles. There are two mounting plates and holes have to be drilled into your stock spindles to mount the caliper bracket to them.
also for sale with these I have a pair of later A-body big ball spindles that are already drilled and setup for the caliper brackets.
As for the master cylinder there is not one included in the kit. wilwood recommends using their master (of course they do) and proportioning valve.
