As someone that just built a 1988 Suburban DD, I agree with Bluestep on this one. I found that if you replace both the door/window rubber, then use the following products and thought process of sound deadening/temp control, the factory AC will work great. The standard 350 and 700r4 are tried and true, parts found on any street corner, and purchased as a new crate engine and trans rebuild, you will have a 50,000-100,000 mile warranty to boot! You are going to get a certain level on noise out of the doors based on the door panel design (only covers 2/3rd, thus the reason they now use full door covers in new cars)

Start off reading information about sound/temp control here:

I then used the following products in the floor, doors and roof for sound/temp control.

Not saying I'm right, I'm just lazy and hate reinventing the wheel.
