How Do I Fix This

Dang Rusty! What are you doing up at this hour? I agree that we are dealing with late 60's technology and tolerances, but damn that seems like a big difference in clearance from one side to the other.
I guess my car was on the production line on a Friday at about 4:30pm.

I would just get a port a power and a length of 2x4 and jack the narrow side out to match.
