I don't have AC and that idler pulley is just in the way. Is there a way I can make things more compact? I wana be able to get at my sparkplugs with no problems. I already started getting parts together to reroute the heater and smog hoses.

I would put a York on there for on board air.

Yup, go with a york. I know where you can get the parts needed :D
