f-250 Rear Diff Help

i Have an 1982 f-250 4x4. i was trying to figure out the front and rear gear ratios but could not find these anywhere. On the door jam the axle code reads
C72 6G8

But i took the badge off the rear diff and it read

3 54 E2TA TB
605086-6 LS

Could someone please decode this for me.. Thanks alot

3 54 E2TA TB

You have a semi float Dana 60 in the rear, with 3.54 gears and a limited slip, and from that axle code(C72) you have a limited slip front also, probably a 44HD judging by the light rear axle in that truck.

If you have a LS front and rear you are pretty lucky. I wish mine had a LS in both axles.

He lives in Canada, so I assume he will get to drive it in the snow. I would like for him to write back in with his experiences with it since it has the limited slip in the front.
