Well I've searched and searched but still need advice. I was having trouble with my reverse popping out and decided to do the "fix". I flipped the synchro sleeve replaced the blocker ring and installed bronze/brass fork pads. I noticed it didn't easily go in gear with the rear casing off. I installed the rear housing and shifter to check it out. Shifts 1,2,3,4 fine. Reverse fine. Just no 5th or 6th! I didn't mess with 5th or 6th. What is up. Ideas?

Thanks guys.
