Question A/C Compressor dead. smaller belt or bypass pulley?

I have a 1997 F150 Lariat with 5.4l V-8 and was told the A/C compressor is broken and has been somehow disconnected so if i select A/C from the dash, it won't be engaged. The actual compressor is still installed with the serpentine belt spinning it and i think the bearing in it is starting to go bad.

I've scoured these forums for a cheap solution (I don't need A/C) and it looks like i can either use a serpentine belt from a non A/C model truck (79.75 inches instead of 99.3 w/AC) or install an AC bypass pulley. The shorter belt seems much easier/faster/cheaper but from the belt routing diagram, it looks like the AC pulley has to be completely removed. Could somebody school me on what they would do in my situation? I don't need AC and want to keep the cost down.

Thanks much!

You will need both the bypass pulley and the shorter belt.

By that time, you could have already replaced the pulley and keep your current belt instead of castrating the system.

From the diagram on the shroud it looks like the short belt and no A/C Compressor would work fine. Where would the bypass pulley go if i need both the short belt and the pulley? Thanks for the help.
