Could use some advice on 5th gear
 

1997 2WD. 5 Speed manual.2 questions if allowed.
1) I have the 5th gear is loose blues. I have the new gear. Before I replace it, My question, is has anyone found a way to keep it from coming loose.

2) I am redoing my interior, dash, rebuild front seats, led lights etc. Question, I would like to reduce the noise heard in the cab as much as posible. Will have it pretty much stripped, so access is not a factor.

All answers appreciated.

John
