Hello Mopar Brothers and Sisters. I have an 8 3/4 rear end in a 489 case with a suregrip. At some point I would like to have another for a spare or at least the carrier. The question of the day is. If I happen to stumble across one, Is there any way to identify if a 8 3/4 rear end is a suregrip by looking at it (is there an identifying mark) without taking the cover off? Thanks in advance Ron D
