I have 1980 4wd 5speed. reverse and 5th were sloppy andgot worse until I can no longer find them. Data plate says Model RN. L43 G1.02 A51. All the data Ive seen says the L43 was 4 speed. Guy I bought it from says tranny is stock. It looks like theres 2 nylon bushings that would wear out causing these symptoms but cant find for this year. Also wondering about the short throw shifter kits... Anyway Im trying to figure out what I need to fix it. Im really new guys so please bear with me. ANY help greatly appreciated!
