Identify this Master Cylinder

Hey guys, I'm hoping someone can help identify this Master Cylinder.
I already did a search. Didn't see one that looked like it, but a lot of the pictures were missing.

It's the only one I ever noticed with the larger disk reservoir in the back, not the front. I can redo the tubing, but if someone can identify it, it would save me a lot of trouble.

Thanks

 

looks like a mid to late 80s gm truck master to me

 

Granada or Mustang II also?

 

Mid 80's Ford I would say because of the large reservoir in the rear.

 

Keep em commin

 

Not sure where in norcal you are,but in san jose there is a place called B&A friction and they can match the casting number.

 

Hi Ron!
It's off a 1985 Ford truck.

 

Hey, thanks!
How's the A?
