I have a '92 RS L03, M39 (5-spd), GU4 (3.08 gear). I see 2 different sizes of ring gears (7.5 and 7.625) which one do I have?
Any help would be appreciated. Just shattered my clutch, and also have strange movement in rear when I take off (even when not breaking traction).

Thanks

 

7.625"

 

7.5 and 7.62 is the same, for some reason gm decided to change how they named the part and confuse everyone.

 

Thanks guys, yes it is a little confusing, but GM is good at that.
I worked at a dealership for several years and they were always throwing a little wrinkle in here and there.

Thanks
