No, I didn't do a burnout and see two stripes I just bought a 91 NA(I know what forum Im in, you guys have more LSD experience than NA people) and dropped the motor. I've seen LSD tranny's before and this looks just like it, but I had no idea 91 NA's had that option? They are definitely NA hubs and axles on the car, so the tranny is definitely an NA tranny. Can anybody shed light on this for me? Look at what I found when I took out the axles.
