I just picked up an 86 F250 6.9IDI with a 4 spd. The shifter on the transmission is pretty sloppy and after an initial search on this site and online I couldn't find a shifter for it. My question is do they exist? I did find a Trans to bellcrank lever rod and a trans shifter insulator bushing, would changing those parts help tighten it up? Any help is appreciated!
