12v Cummins 47re to NV5600 conversion
01-05 I believe. It might be 04. Pre 01 5600 had smaller input shafts and some other undesirable features. You'll also need a spacer for the starter and a crossmember from a newer 2nd gen. I'm not sure when they started using the newer style crossmember that had 2 slots of holes for both trannys. Probably 98 or 99.
The 5600 is about 6" longer so your going to need some driveshaft work too.
