I would think they would have been made by delco remy but I could be wrong. Are you dealing with a big name auto parts store if so try a mom anf pop store and tell them what you would like.

**leddzepp** · 09-04-2010, 12:56 PM

Mine are Delco, but I have no clue what the part number would be.

great advise guys...... big thanx,dave

The delco disk/drum m/c was the dual bail type, the bendix uses the single bail. Either m/c will work on either booster but to be correct you should try to match the booster and cylinder. For the record the delco booster was cadmium plated (gold) and the bendix unit was painted black.

oldblue1968chevy · 09-04-2010, 11:20 PM

so if i get the delco one, brake fluid wont bother it?

Old blue the fluid will still hurt it just not so quickly, also usually the rebuilt units are not replated, so it will prob. be grey or some other flat looking color of dark.
