Yes ,741 carrier.

Wont know if its limited slip until you jack it up and see if it is.

Its a 741 8 3/4 case but may or may not be a sure grip. You'd have to look in the carrier to see

 

[LongR]

So 741 8 3/4 cases are not all sure grip ???....It was an option ?????

You have to jack it up (or look at it if it's on the bench) What car is it in?

Unless your car came with a Dana, a sure grip was always an option. I would think 741 open diffs would far out number 741 sure grips.

Toss it in the air and spin a wheel or axle. If they rotate in the same direction, LSD. If opposite, open/non/pegleg.
