a 3.9 was an option but I have never seen one. Also a 4.89 was available. I think if you check closely you will find it is NOT the same pumpkin as used in the M37/PW, but it can be made to work. If I remember correctly the R&P is smaller that the M37/PW gears, however the splines and spiders are the same. It also uses the Lockrite as the M37/PW. Their is a drive train mod guide out that covers the change.
