I have a 3 speed and a 4 speed differential available. Both have 330 ratio. These both came in a car purchased, the car was a stick, now an automatic. Both ring & pinons look great, bearings run smooth and no sign of damage. The part numbers are the same yet one shows GM1 and the other GM2. The 3 speed (white one) has the letter "P" stamped in one location, the other a "1". The 4 speed (blue one), "Y" and "4". (Last photo is the 3 speed)
Asking $250 each (obo) plus shipping. Thanks.
