like most civics and integras my clutch master cylinder is leaking. Problem is that my car is from japan, RHD, and the part is different. The internals seem to be the same but the spots where the lines connect to are not the same as USD versions. Anyone know how to rebuild these? If there are O-rings inside I could get new ones but I can't figure out how to get the piston/seals out of the unit. tanks
