My experience is NAPA will often have the parts that no one else has. And as a former NAPA supplier I can tell you they are particular about what they buy. Unlike some retailers NAPA's first priority is quality, second is price.



Thanks for the info. I'll give Napa a try. Cardone has basically said it is no longer available. So as stated before I may indeed have to have this one rebuilt. The guy I bought this car from broke the LH lower front stud off removing the old master cylinder. My understanding is the problem wasn't there before the change. Could that cause my leakage problem? You can hear it leaking from inside the car when applying the brakes.

Anyone ever use Booster Dewey? Going to give him a call tomorrow if I strike out with Napa.


It appears that Booster Dewey and Mancini Racing are my options if Napa can't get one.
