Need Help with Lifted 86

[timzrides]

I ended up with a 86 shortbed 4x4 in a trade. It has a 6" lift and transfer case for 700r4. i'm new to 4x4's so here is my problem. the rear has 4 inch blocks. What did they do to raise it another 2" In the front, what did they do to get the 6" lift. I ask these question because I believe I want to bring it down some. i'm thinking i would prefer a 2" lift. How can i accomplish this, remove the blocks in the rear and do what to the front. also, will anything else need changed out, when you lift does driveshafts change. what could this person possibly done. it currently has no motor or trans in it now. thanks for help and advice!! tim
