Shorten A-body axle or widen well

Hello All,

I have a 66 valiant 200 4 door. I'm dealing with a problem where the Cragar rear wheels (15'' that are wide outward - 4" smb) i have are rubbing on the fenders. There is very little room next to the fender from the tire... maybe a 1/4 inch but with load or a bump i hit.

I'm committed to the wheels, and i'm wondering if i should shorten the axle by an 1 1/2 or expand the fenders. Cut them or bang them out...

Is there any chance someone knows of a rear axle that would work in an A-body that would be an 1 1/2" or 2" shorter?

Thanks in advance!
