The measurements from the outside of the rear tires to the lip of the fenders differs by 3/8th” when comparing the left and right sides. (At their closest thevdistance is less than 1” on the drivers side and ~1 3/8” on the passenger side.
I never noticed it before. Suspension ears are ok, camber looks ok.
Is this normal?

not unusual in these cars, hand built and lots of variation.

but... i would add, make sure to check the camber wirh an alignment, that could make a difference too

Totally normal

usually the opposite..

I’ve seen narrow body cars with 7” cookies peel rubber from the side walls on the passenger side but never on the driver side.
