I've had this naming problem before...in any case, its the brass junction
block just below the brake booster...Does anyone think this will work (with
some minor bending of the brake lines and "adjusting" the mounting bracket:

Ironically, the first one I had in the car was bad so Ron McCall was
kind enough to send me another one. That's the one I had rebuilt by
Muscle Car research and which is now leaking badly from the port where
the brown brake pressure differential switch screws into. Does anyone
think this one will work (with some bending of the brake lines and
re-working the mounting):

Joe,
I had one I sold to Larry Stock years ago. He has several I think.
To be clear, you are talking about the shuttle valve/junction block where severa
l brake lines and the brake light switch connect, not the pressure reduction val
ve in the front brake circuit.
