tundra onboard air

[mtntoy]

I am going to install onboard air on my tundra and I am going to use a york upright compressor.  I am thinking that I will go just to the right of the current ac  compressor and below the battery.  Any one out there who could give me there info on what might be better could help.  I am thinking that I might just get a new pulley and stack it on the ac pulley, then route a short belt from there to the pump.  Is this the best way to go or should I come up with a way to use a longer serp belt and direct it to the york?  I have yet to get my hands on the york so anyone with a good one for sale let me know too!
