Here I go again... 72 GMC 4x4 build up

[ericpost]

Back in 1998 while on a Business trip I bought a 1972 GMC Jimmy in Phoenix AZ and drove it to New Hampshire where I live. The truck was a little beat up mechanically but the body had no rust and was in great shape. It came with a Corp 14 bolt rear, Dana 44 front, 4 wheel disk brakes, NP205 T-case, SM465 Tranny, Hydralic Clutch, 2 Inch lift, 33" tires on nice Aluminum rims, and a Small Block 350. I quickly tore the truck down re-did the interior, repainted it, and rebuilt the motor and suspension. Since then it has been a great truck that never has seen snow and has seen some mild off-road use. She is still in great shape but I'm starting to get that feeling again and the truck needs a make over! I really want to get back into more serious 4 wheeling (my son is 7 and loves it!) and I want to use the Jimmy to do it. My first thought is I want to lift the truck a total of 6 inches, get 37-38 inch tires, change the axle ratio to 4:56, 2" reciever hitch front and rear, winch that will mount to the reciever hitch, Spare tire carrier, Body armor, and ??

For the past few years I have been working on my car and Harley so I'm a little out of touch with the 4x4 scene.

My question is what tips do any of you have on this build and where do most of you guys source your parts?

BTW:
-- The lift will be with ORD shackle flip kit and 2" blocks in the rear and springs in the front.
? Am I going to have problems with drive angle?

I'll post pictures of the truck prior to tear down later today.
