Need someone to look at this pic and hopefully tell me what I got I believe it is a dana 60 this is 8 lug 3/4 ton axle on 71 Chevy Blazer. Is it a locker, posi, or ???

It looks like a dana, open diff. ( Not posi ) If it's a rear end 8 lug it's probably a dana 60. If it's a front end it could be either a 60 or a 44. There will be numbers on the opposite side of the diff. case shown in the pic. ( 44F or 60 )

I'm sure it's a dana 60 amd it is the rear, I jacked up the truck had all 4s in the air and when I spun the tires they turn in the same direction on front and rear, my thought was if they do that you have posi or locker but I have no clue about axles of Diffs.

Both tires spinning in the same direction would be a possible indication of a posi, but the pic dosen't indicate that. Are there any clutch disks inside the ring gear ??? or just another side gear ???

I don't remember the Diff is all back together now it must be posi cause if I do a burnout, short one with 35"s, it does spin both tiresand it will kick the truck sideways.
