transmision linkage

Okay first of all, thank you to everyone who has helped me this far. I’ve finished rebuilding my transmission and am pretty confident in it at this point in time. Truck drives forward for the first time in 24 years! I have one problem however, it seems to be shifting wrong. Not late nor early...

Two questions on a 88 Eddie Bauer B2 that I was wondering if anyone could help with. 1) the transmision shift linkage is missing the keeper sleeve that keeps the linkage on the shifting backet. is there a way to get one of those or do I just maybe drill a hole in it and put a cotter pin on...
