since no one asks... small or large rear brakes?? cannot mix match..
I know this is maybe not what you're looking for but why don't you just go with rear wheel disc brakes?You have two options for that, either buying the kit new from suppliers that sell this (like German Auto Parts, The Parts Place, etc.) or gathering the necessary axle stubs and brake parts from a junked vehicle that had factory disc brakes. This is something I have been planning for a long time, GTI brake swap, I have all the parts coming so I may finally get around to doing it. If you still want the drum brakes I would ship the entire brake backing plate to with all the hardware on it, assuming they are the right size and that you still need them by the time I get to making the swap, which may or may not happen this week.
