Hi, I recently purchased a used 1993 Aerostar with a serpentine belt bypassing the AC. I'm assuming the previous owner chose the lowest cost solution to solve an AC problem. I would like to restore the AC with a minimal expense, replacing only the necessary parts. There seems to be a variety opinions about which parts are required to restore the AC.

My wish list of replacement parts is the following:

1) AC Compressor
2) AC Receiver Drier
3) AC Orifice Tube

I was wondering if it is necessary to replace any of the following parts:

1) AC Hose Assembly
2) AC Pancake Filter
3) AC Condensor

Other than that, the only thing I know about the AC Compressor is that it looks like it has been disconnected for a extended period of time because the pulley is rusted on the surface grooves.
