I don't know what my gear ratio is on the rig. Everything is in the sig, I tried the conversion but can't see anything stamped on the diff. cover, and on the door where it says "Axle" there is no number ....
I can tell you this though, at 55mph I'm at about 1800rpm, and at about 71mph I'm at about 2600 rpm. Both on fairly flat road.
4.10's? I dunno how to figure it out
