I posted this up in the brake section, but not much traffic over there and figured it would probably be a better question to ask over here! I searched around and had no luck of reverse searching the part numbers, so here's my question!

So I picked up a JDM CTR/USDM ITR 5 lug swap and one of the calipers were seized (left rear). Before I head down to pick up a re-manufactured one from the local auto store for $120+, I was wondering if anybody knew of any other OEM calipers that were interchangeable (same part number/size) that a local junk yard would likely have in stock (going rate of $14).

Any help would be greatly appreciated
