On my 71 challenger the right side rear wheel sits out 1/2 inch further than the left.. i noticed this on my 70 and 73 challengers i have owned in the past. Do any of your e-bodies have this problem?
I noticed that my engines would sit more towards the right side of the compartment than the left. I was told that this was to align the offset of the pinion gear. Looking at the rearend and the offset of the pinion, I'm guessing that is why the rearends are set 1/2 inch towards the right. Just an observation.
