Another master cylinder question

[Conchyjodyoos]

So my car developed a brake fluid leak from the m/c, I pulled it off this afternoon but I'm having a hell of time finding a replacement. I've searched the forum and it seems most people have a mustang II or corvette m/c installed. Mine has two different size reservoirs but my hose connections are facing the engine. The bendix part #2231591 Google search hasn't turned up anything either plus the local auto parts stores are baffled too. The car has 11" four wheel disc. Any ideas? Thx

That looks like it! Here's where I get confused because I'm a newbie, it says the bore is 1 1/8" but the part of my m/c flange OD that goes into the booster (not sure of terminology) is 1 1/2". Is the advertised bore the id?

[spdbrake]

The 1 1/8 should be the cyl id. The complete booster / master cyl Assy is PN 50-3208. Approx $130.

Awesome, thx

Not to confuse matters, for what it's worth because I don't know..... BDR &CR the same(?) you describe you CR brakes. This unit does use the Corvette booster /MC.
What you are describing and can't locate is one in the same M/C.
You can order it with left, (fender side) OR Right (Engine side) Ports.

After contemplating changing the whole booster/mc assembly I decided to replace just the mc with the Napa unit, works great and no more leaks. thx for all the input.
