1970 K20 Restoration

[K20rookie]

Ok, so I'm ready to get this project moving again. Got a little sidetracked the last few months. Tom up in Phoenix has a 14 bolt rear with detroit locker and 10 bolt front with discs in 4.10 gears for $700. Came out of a 76. Anyone have any advice on the 10 bolt vs a d44?

Also I'm looking to buy a lift kit and get that installed on the frame. Would like new springs all around, probably 4" lift with 35's. Thought some of you might have advice on what companies to look into. Skyjacker, Tuff Country? Let me know what you would recommend. Not looking to do any hardcore wheeling, just occasional off-roading for hunting, etc. More concerned with ride quality than anything else.
