after going to look at the unit i found it had 8 lugs. i need 6 lugs. im looking to find a one ton rear that has the third member to change out the ring and pinion and will acomodate duallys. as of now i have a split timlin rear and a ring and pinon change cant be done on the timkin. i know there is a rear out there somewhere from a cc and ec gmc model years.
