I have been looking for a 4.10 rear with limited slip for my truck and came across one on craigslist. The guy had already got rid of the truck so I got the numbers off of the tag on the diff cover. He said the axle was out of a 1995 F-250 and he thought it was limited slip, I am not sure on the limited slip part with out driving down to look at it so I hope one of you guys can decode this for me. Thanks, and if you have a good axle tag decoding link please share it as I can't find one.

The tag reads

s110k and 4 10 10 24m1s

 

they are 4.10's...and an open carrier...if it was LS it woulda been printed 4L10 10 24m1s
