86 C10 in the Works, Porterbuilt Questions...

[XtremeBowtie]

Let me say, I have lurked on the forum for a couple of years, researching and gathering GREAT info.

Story so far: The truck is an 86 2 wheel drive, short bed. I intend to install Porterbuilt dropmembers front and rear. Plan on laying rockers after I cut / roll the pinch weld. I am torn between running 22's all around or going with a 20/22 combo. But before I get too carried away, I have a few questions:

1: When it comes to being able to lay flat on the rocker panels, is there a body drop needed after installing Porterbuilts dropmembers front and back, or does the body of the truck sit lower than the frame rails? (don't have access to truck so I can't see for myself).

2: I've seen trucks on here running 20's or 22's up front but most of them have the heater box out and smoothed the firewall. I have also seen the term 86'ing. Is the AC / heater box different on 86-87 trucks? If so, is it safe to assume I could run the factory AC with such a large diameter tire?

3: With Porterbuilt's front dropmember, can I run different A-arms other than ART's? I would like to run Suicide Doors or Porterbuilt's arms. Nothing against ART, but the ART arms I have on my bagged S-10 pop and creak like crazy! I've greased and greased, but it only helps temporarily. Plus I like the design of the crosshafts better than ART's. SD / Porter crosshaft ends are tapped while ART's are threaded requiring a jam nut (which constantly needs to be tightened).

I know it's annoying to read all these questions, but any advise is greatly appreciated. I've researched for a while, but I've not benn able to find complete answers.

Thanks for the help!
