Ok guys verified I have a dually 14 bolt cover was counted to double check but it has 4.09 gears now my are 14 has 3.73s so my question is can I swap that gear set over to the dually without any issues? I also ordered the full gasket set for the 4bt ,a rebuild kits with bearings seals gaskets and synchros, and from what I found online the gasket kit from a np201 np200 np205 all fit the 202 I bought one with the 10 bolt pto gasket. I also bought a front and rear axle swap kit for the gm 14 bolt and the GM D60 from Barnes 4x4. It includes the perches plates u bolts and shock mounts. I now need to locate a new or used turbo for sale or trade that will work well with my intended setup and an intercooler.
