What is my stock differential?
I have a '90 RS (305) auto. I'm interested in SLP's take off posi, but from doing a search, it sounds like they came in most '89 and up 28 spline axels. Does anyone know for sure? Thank you

If your setup is stock then the SLP posi will fit your car. However you will have to get a bigger sized ring and pinion (3 series vice 2 series).
What a better time to upgrade to 3:42's!!
