Locking/Lim. Slip Diff. on 03 Sierra

I'm wondering if 2-wheel-drive Sierras back in 2003 had an option for a locking differential or if 2WD's only got the limited slip.

I asked a dealer about this and he seems to think that the G80 locker wasn't an option on the 2WD but was often standard on 4 X 4's.

I'm having some confusion on this matter because on later models a G80 locker was a package option on some 2WD's (i.e. the Nevada Edition Sierra).

Would anyone be able to shed some light on this?

Thanks John, and Z71 for your responses.

I guess I ask specifically because I wasn't aware that GM used anything except the G80 locker and was a tad surprised when this dealer told me this truck I'm interested in buying had a limited-slip diff.

Essentially it'll be the determining factor as to whether I buy it or not, as I live in Saskatchewan and a locking diff on a 2WD is the minimum one usually needs to get through the ice and snow with any degree of comfort.

I suppose I need to frame that in the form of a question.

Did GM use limited-slip differentials in their 2WD trucks (around the 2003 MY)or did they only use the locker?
