833 Rebuild - 2nd Gear Grinds Going Up and Bumps Out Decelerating

Not quite sure, but I thought that I read something when I did my '67 18 spline, about a year and a half ago, about being careful while doing a certain procedure, or it could lead to the same problems you are encountering. Syncro/dogs issue ?? A guy on here is a 833 guru, maybe tomorrow he will jump in, or I will try to get you his screen name. Clutch adj will not cause this. I always adjust that by feel. You can use a drill bit to adjust shifter.
