Robert here is what I used for On Board Air on my 03. It involved lowering the alternator and using a different belt and a special CAC intake tube.

Kilby doesn't make one for the 12 valve but I originally bought the special alternator pulley from them and was going to make my own brackets to mount a York air condition compressor on it's side above the alternator. I saw pics of it on here I believe. It puts out about 160+ psi and works great. Here is what my kit came with: ::Kilby Enterprises:: I managed to get it on sale for "only" $1050 USD.
You are right about where do you stop once you've started. That was one of my concerns in doing the 84 crew. I knew I would end up rebuilding the entire truck. BTW what year is your truck registered as? Does it have a 93 VIN? Shadrach
