SS blazer a/c comp mount bracket question

[68c10airstream]

just received a new SS trailblazer a/c compressor for my 68 c10 with a 2001 5.3. The compressor mounting holes don't line up on the factory 2001 a/c mounting bracket. I'm assuming that i need the SS trailblazer mounting bracket from probably a 2005-2007? The new compressor is a factory sanden trsa12b. The suction and discharge ports sit parallel to the engine crankshaft and are indexed point up high as this was my choice so i didn't cut the frame out. If i have to get the trailblazer bracket, does it have mounting holes on the front flange for the belt tensioner? Any help with pics and info would be great. Thanks, Brian F.
