i think a spacer will be required going a full number higher to reuse your carrier but they are cheep..lots of aftermaret vendors make gears for 8.2" ten bolts all you will have to worrie about is what ratio you want ..then get a ring and pinion install kit with all the bearing and seals and your good to go....Also it would be a good time to rebuild the posi if it is one that way you wont have to mess with it for a long time....Cheers
