When ordering my neaw gears...where have you all found good prices? Summit? Is $150 labor for the rear and $200 for the front a good price not including the parts? I guess that is $350 labor not including the parts I have to buy. And what parts do I need to buy(gears for 2 diffs + the installation kit...bearings etc.)? I'm installing 4:56 ratio. I'm looking for a good place to order this stuff from. Should I consider anything else when doing this change...I've got stock diffs on a 90 Jimmy. 1990 GMC Jimmy 350/TH700R4/NP241/10 bolts, 4" skyjacker lift, 35x12.50R15 BFG All Terrains on 15x10 AR Baja's, Flowmasters.
