im looking for one in south eastern AZ my friend said one wheel wonders suck

 

if i'm not mistaken a positronic rear end is the same thing as an LSD.

So you need to look for any year GSL or GSL-SE.

 

positraction is chevy's name for Limited Slip Differential. Our cars are not chevys, so the diff is just called LSD.

Positronic is the term coined by Isaac Asimov for positive-charged electrons in antimatter. Don't try to get positrons for your diff, or people will think you're on LSD

 

oops, my bad
