So, after a more careful examination of my gears during a drain/fill, I suspect I do NOT have 4.56's as advertised when purchased, or possibly WORSE different ratio's front/rear. I was going off of SOTP and what the PO told me when purchased. The front in particular I am about 99% sure are 3.73:1 just based on one full revolution of the ring to under 4 turns of the driveshaft.

Anyways, here are the stampings on the ring gears... ANY HELP in tracking these to what they actually are would be MOI appreciated.

FRONT-

10 2 69 DANA 18575 A3D85 41:11

REAR-

3817778 11:41 GM11752

Thanks in advance for ANY help!!!
