Yes the passenger side on a supercharged is shorter. That’s why I was saying if by some chance there is a non supercharged transmission put in at some time and you are trying to fit a supercharged axle in that it would be short. Unlikely this is the case though.

I dealt with the same crap from autozone. On my 04 Comp G. I ended up finding a lower mileage stock axle from Morads and putting it in the right side and bought a brand new OE axle for the left.
