Got it, anybody have information on body shifting and how to do it correctly, like where’s the best spot to pry/pull on without doing damage to the car? Pics would help.

Look at the gas tank before you start to grasp how little it can be moved.

But (I'm guessing) plenty of clearance on the inside? Indicates rims are of the wrong offset...

One side will have more clearance on the inside than the other, and the other side will have more clearance on the outside, that means the body is on crooked. This has nothing to do with wheel offset.

The drive train does not go down the exact center of the car. The steering ,and brakes require more room than A/C. I'm sure some bodies may be crooked due to accidents etc. but ,not every single one of them.... Same reason there's less room on passenger side for headers.... That's why when one measures the intake to top of fender on driver's side is 31" ,but only 29.5" on passenger side.
Or ,maybe Chevrolet put all their engines in crooked too.

There are slight alignment issues with the drive train, but the rear is equidistantly placed from both sides of the frame (the axles are the same length), so the rear is supposed to be centered in the frame. The universals take up the variations in internal alignment (production cars are not perfect like custom one offs). Most of the bodies are off to the left in respect to the rear axle. The room on each side for headers was not considered when the cars were built, so being dissimilar from side to side is not unusual, and being a tight fit has nothing to do with body alignment. If you check, the dual exhaust pipes do not take a mirror image path to the mufflers. This is because the car was not originally designed for dual exhausts.

A quarter inch side to side does not make a difference with the stock tires and wheels. No one would notice it if they did not try to put oversized tires on the car. When you get to the point where there is little "extra" room for things, is when you notice that there are issues with body alignment. It is not all that hard to "fix" the body alignment, so just loosen it, move it, put the big tires on it, and be happy,
