late model power steering pump removal

[rodstored-72]

hi guys,
i have '72 chevy p/u with a 92 suburban serp. belt setup on it. i have a flex-a-lite twin fan setup as well. my question is basically this: how do i remove the pump?? i am hoping that there is someone else on this forum that has switched to a late model serp. setup that has had to do this already & can give me some very appreciated insight!! i am really at MY WITTS END!!. i don't think that there is enough room to remove the pulley 1st. maybe someone can give "step by step" instructions for the order to do things anyways. i am able to get to all the bolts except for the one behind the pulley on the pass. side.

if anyone here could (would) help me i would be very greatful!!!

thanks for the time to help!
