Sorry about another t-lock and gear question. However, i couldn't find it with the search. I want to know everything i'll need for a t-lock install (to be done by professionals). I have a 96. I have the lock and the 4.10 gears. i don't know if it matters but it is a 5 speed. I also have 18 inch tires. Basically, i was looking for a way to fix my speedometer and tach (if it's off, i don't know it will be). Anyway, thanks for the help. Just trying to get everything i need.
