Need to locate a clutch master cylinder for my 1985 Task Master Fire truck.

What is your question?

Slave cylinder is a Lockheed, the master is missing so I don't have much to go on. The mounting bolts are 3/8" diameter on a 3" center mounted in the horizontel position. It uses a Dodge slant 6 engine with 4 speed manual trans. The truck is about the size of a Subaru SW for use in a shop. Anyone got any ideas. Thanks Jeff
