Ive read all brake/ master cylinder posts i could find. My problem is my new MCA76162 master cylinder(which i was told is the equivalent to the desired F66857 master cylinder) mine does bolt right in but the pushrod which is original is too long. Either i got the wrong master cylinder or pushrod through the firewall needs to be cut down. Before i move forward and cut the only pushrod i have, i want to make sure I'm not making a mistake.
