nope the rod is perfect. like i said the new master cyl is drilled shallower then the original 73 up style. that same distance as the spacer. i have the wilwood master cyl. i believe the 85ish diplomat are built the same way.
and how hard you you be pulling the pedal up to get it past the brake light switch?? gotta really yank it to do that i would imagine. that thing isn't just gonna fall out i can tell you that.
