I have a Prelude here in New Zealand, and its a Japanese car (it was imported in 1998 to NZ), and it needs a new brake master cylinder. However all of the parts stores need more info than I can give them without taking the darn thing off. Apparently there are multiple parts, even though they know the engine (B20A) and chasis (BA5), they still come up with two parts, both with slightly different bores and different prices.

So how do I find out which is correct for my car without removing the original? Oh the current BMC on it has ALB stamped on it (although I am not positive it is the correct model, which might be the problem for all I know).

 

Anyone?
