77 C10 LT1 power steering question

[77c10]

I have a 77 C10 2wd with a LT1 crate motor in it. I want to add power steering to the truck. Currently the only accessory I have is the alternator and it is mounted low and to the left of the motor with a single belt that is driven off the crank pulley. My question is, can I get a stand alone bracket to mount the power steering pump and if so, are there double bottom pulleys available to run the PS pump?

Thanks!
