3.90 Ring and Pinion Set 65-82
I just removed a very nice 3.90 ratio ring and pinion set to go back to my cars original 3.36's. The 3.90's were installed new over 22 years ago and the previous owner passed away shortly after . The car went into a 22 year storage shortly after so the gears have had very little use and still look perfect. $200. and I will include shipping to anywhere in the US for forum members .

Not sure . I was told by someone that knew the deceased that the gears were put in new ,that they were 3.90's and it went into storage shortly after. The work was done on the car by a performance shop including all of the engine work so I would assume that they were quality gears , maybe GM but I just don't know for sure.

GM gears will be marked GM with a part number and the tooth count on both the ring & pinion
