Moraine Master Cylinder

I have a 1972 GMC C2500 with front discs, trying to find a rebuild kit for the master cylinder. The one I got from Dorman was to small (1.125"), I need 1.25" piston. I can't seem to find anything. PN on the MC is 5472003, anyone know of a source or if another PN fits in it's place?

Re: Moraine Master Cylinder

The casting number 5472003 master looks just like the one on my 1972 Cheyenne Super 20.
