im still searching and can only find diagrams with the pressure regulater in,these are 71 on diagrams
that sounds like what ive got,thanxs bud.Speedy Jim said:Your '68 may have originally been fitted with a single-circuit
master cylinder. That has one outlet pipe and the TEE
would have been used to split it off.
The new master cylinder has 3 ports (1 port near the pushrod for
the rear circuit and 2 ports at far end for front) so the pipes
connect directly. It is a dual-circuit model.
