master cylinder help needed

I am using a 48 ford truck crossmember ( pedals and all ) on my "A" frame. The master cyl is shot. not worth rebuilding. Is there anything I can get that will bolt on. the bolt pattern is two on top and one on bottom in a triangle.

 

Sounds like the early Ford 39-48 m/cyl. 48 F1 being the new design that I've never played with. You can get an adapter to mount a modern 2 bolt dual resevoir m/cyl to the trianglular bolt pattern on the frame. Dick Spadaro carries it.

 

That will work. Thanks, this board has all the answers.
