Jerry,
I am going to stick with the original trans for now, ultimately it is getting replaced with a SM465 with a NP205 transfer case. I have matching Dana 60's to put in it sometime this summer. THey have 4.88 gears and are all painted up and ready to go with new Axle seals, u-joints, and brakes. Hope to be able to put 37's under it with enough clearance. A local spring shop came to look at it and they feel that with the correct lift springs it can be done correctly, and safely. This truck is a factory longbed stepside 3600. I love it and can't wait to drive it on the road.
