WTB 1990 JDM SW20 turbo rear left brake caliper piston
Outside of piston can be pitted, I'm interested in the screw/spring contraption inside. Not sure if left or right side is important. The piston I took out had "R" on it. And it was on the LHS? Maybe the "R" meant "rear"? Should have been obvious, the rear ones have this handbrake screw stuff in it? The caliper on this year model is marked "16V" on the casting.
