I have an on-board air system in my jeep, using a "saden" A/C compressor. I fab'd it in. I would like to install a simular system in my truck, maybe one day I will, but for now I use tiny electric airhorh pump & tank.
For you, mounting to the 318? you should be able to locate all the required bracketry (if you don't have them already) from a dealer or junk yard. Different clutches are available for the compressor, I would not weld anything to the stock truck pullies, just change the clutch on the compressor.
I don't know for sure, but I would suspect you can find longer or shorter serpentine belts to fit, once you have it mounted.
A few other things to consider. A pressure cut-off switch. The compressor in my jeep is rated for 325psi (airtank only 150) I have the clutch wired to a pressure cut-off switch. Also, a pop-off valve, in case the switch fails (it open's at 160psi and it's freakin loud when it opens!)
Be glad to answere any questions, e-mail me or post them.
