NARROWED REAR OFFSET?

Nope, the center carrier has the pinion offset in it. Pinion is not in the center of the carrier.
I'm confused... Ford 9" have different length axles and the center of the hump is not CL of the car and this results is the pinion CL is center to the car's CL.

Just looked at Dr. Diff calculator
Stock Mopar pinion offset = same length axles

0 pinion offset = different length axles

Maybe I'm missing something here but doesn't pinion offset mean offset from car CL as per tip #2 on Dr. Diff website?

"Tip #2: A pinion offset of "0" places the pinion in the exact center of the vehicle..."

So this indicates that the Pinion of a stock 8 3/4 is 1 3/16 off center from the CL of the car, does it not?
