The nut isn't the problem, Go to Quad 4x4 .com. Its the gear and main shaft. my 94 has a 97 transmission in it (see thread about 230 ford inj. )and I am rebuilding mine now. on my 97 the 5th gear nut was staked and locktited, so 5th gear wore into the main shaft and wore next to it under the output bearing. Quad 4x4 has pictures, mine looks just like em and I bet yours does to(not trying to be pesimistic). Sorry, but on the upside its not aa tough transmission to rebuild and parts are not that expensive. good luck.
