Hello Sir Kilmer,
My name is Naba from India. I have a Willy's 1948 which is modified a little internally! The problem is that the gear box is stuck and while driving the gear is not changing into 1st gear or any other gear not even reverse....! How should I solve this problem?

Will be waiting for your reply,

Thank you,

you will have to take the gear box apart, it's broken internaly, probably a bad dog leg

Sure, so do I have to buy a gear box?
