hey i had a whole in my frame where the gearbox bolts to and had to weld a half inch plate on it. so i was wondering do i need to adjust the adjustment sleeve or anything else to make up the half inch difference.

 

Well, you wouldn't have to if you welded that plate on the outside of the frame.

 

The gear box is 1/2 inch inside where it normally sets??? Are you having trouble making a right turn? Maybe you can shorted steering link by a half inch.
