Great looking classic. On the note of the 22's a guy I know has one just like yours in baby blue, with 22" superman logo wheels and it also has a superman steering wheel. I assume they are drum brakes, have you tried adjusting(so there is less tension) the brake on the side that its pulling to? Try to keep it as long as you can, I regret selling my Chevelle every time I see an old car on the road.

PS. You just dated yourself there.
