[altereddezignz]

Hello everyone. I am new to this site and have already learned alot abotu what i need to know. This is the start of my new project. It is a 1986 Chevy c-10 2wd 2 door reg cab. Here are some pictures and a breaf description of what will be going on and in the truck.
4.56 posi rear end
blown 355 small block
Turbo 350 tranny, 3200 stall
Heater and ac delete with vintage air unit.
20 or 22" wheels. not sure yet
Blue and silver/grey paint scheme.
complete custom interior.
possible Z frame.
4 link rear, Not sure either bag on bar or bag over axle.
stock lower control arms in front.
Four 15" l7 subs in bed of truck through cab cut.

The truck needs new cab corners and some work. I cannot complain thought b/c it was FREE... My father in law gave it to me... Now im gonna give him a heart attack and cut it up. (Since he bought it new) LOL...
I do have a couple questions though.
Would it be better to run an bag over bar or bag over axle setup?
When Z'ing the frame will i need to make a new tranny tunnel cover?

The reason i ask a few of the questions is i already have a complete air ride setup, all bags, air control unit, 4 link, and spindles, But they are for a 88-98 full size.

Will the spindles work on the 86 i have.

Well here are the pics.
