Hope you guys can help me out identifying this differential on a 92 RS I can see it has Richmond 373 gears but I also noticed it's got broken springs which I need to replace just not sure what type of differential I have to order the correct parts here is a picture I took hope you can help

 

Looks like a locker kit installed in a standard differential case. It doesn't look like a Power Trax kit or a E-Z Locker. Yukon doesn't make one for the 7.5 that I can find. You might have to do some searching. A better picture from the other side would help.

 

Ok I'll take some more pics

 

That's what it looks like to me, too.

Don't know offhand what kind it is, but it doesn't look real ... healthy. Also doesn't look like the kind of thing that would be worth "repairing". Might be better to just turf it and start over.
