WTB Master Cylinder Replacement Cups/Wipers

[Macdon221]

Good Day All,

I have B body master brake cylinder 2944 376 or Casting 2225621. Ports that exit on the left or Fender side. 1 1/8th bore size.

I am looking for a rebuild kit. But really all I need is the pumper and/or the wiper cups. Everything else is basically brand new never used. It is a NOS unit. One of the Cups is torn.

Does anyone have a source for these?

I know I can buy the whole kit, while scarce it can be found, for for more than the master cylinder cost!!...but all I need is the cups.

But I was wondering if there is another kit out there that the would have the same dimension inside and out for the cups?

It was mentioned that some of the dodge trucks of that era has the same pistons/cups.

The kit numbers and cross reference that I found for the actual master are...

Raybestos MK620
Wagner 59020
3420 117
3420 120
3420 967.
2808 616

Any help help would be appreciated!

Thanks

I wanted to give an update...no one chimed in so I thought I would chime in with my solution...

I found a Wagner F59193 or United K525 or Raybestos MK525 kit for a 70's Dodge truck. For 1 1/8 bore.

The pistons/springs are different length but the cups/wipers are the same inside and outside. Worked perfect.
