the auburn pro would be better but the zexel should be fine. Dont get the auburn that came stock in earlier 4th gens.

So your saying that this will work just fine it was taken out of a S10 and is i great condition

GM doesn't make posi units, companies like Auburn and Zexel-Gleason do. Depending on the year S10 it came out of it is probably an Auburn unit. This will work just fine for a naturally aspirated V6, and should hold up fairly well even with a power adder unless you spend a good deal of time at the track. The Auburn units GM installed are not as good as the Pro series Auburn. If you're making enough power to start burning up differentials however you're probably making enough to warrant a 12-bolt rear.
