A body non 7.25 rear end

Hummm, this concerns me. I was planning to step up to 235s on my '65. Are the tires rubbing the inside of the fender? Is the 8.25" rear end a bit wider than a 7.25"/8.75"?
Ours is rubbing on the outside.
8.25 is narrower than 8.75
An accurate 8 3/4" rear axle width list

TIA
