I think I have one of those "T" PM me if you are still looking for one. Mine had a bolt that attached through the frame on the passengers side and it is made so that a line from the master cylinder goes to it and then a line t's and goes to the left for the passenger wheel cylinder and the line from the right goes to the rear wheel cylinders.

I upgraded mine master cylinder to a dual power master cylinder.

It came off a 1956 chevy 3100
