Another P/S Pump ?

[zach_carver]

I have a 2007 LS2 from a Trailblazer. When installing the motor into a 65 C10 the p/s resevoir wouldnt clear inside frame the frame rail. Im going to reuse the fittings from old sbc pump into the LS pump but im unsure which p/s pumps will fit in my factory accessory bracket and allow more room for clearance of frame. Im looking toward just getting new 2003 chevy truck pump from 4wd that would have used a gear box steering and not a rack. My truck has factory power steering gear box.
