Need help IDing Differential
Hey, I opened-up the diff in my roller 1991 (S5) N/A. It looks like the original open diff since the half-shafts are equal length, however I'm trying to determine what size the ring gear is. A rough OD measurement is 7.75". Is this considered a 'big' or 'small' ring? Take a look.
