AC conversion help needed

[SSLance]

Part #12497698 is an option I guess, but I still would need to find out if my 144 amp alt would fit in it and also have to pick up the $80 adapter plates to put my Sanden style compressor in it (don't want to go back to an R4 comp). I can't seem to find out which style of PS pump it comes with, but I do like the PS pulley wrap. It looks like a much better option than the take off stock serp setups for sure. Thanks...
