Redoing the big block in my 69 GMC flatbed. Putting in a semi-built 454. Nothing radical, but should be a clean 350+ hp. Anyways, while the engine was out I pulled the evaporator box apart, cleaned it out and installed a newer unit where the receiver/drier hangs with thoughts of upgrading the unit to a cycling system and 134a. Already have the new condensor mounted. Where I am at now is getting a compressor and getting it mounted while the engine is on the stand for mock up purposes.
An R4 would be the easiest for placement along with not needing an extensively long belt, but I know it's a so-so compressor. I was also looking at the Sanden style, but that would require the unit hanging over the valve cover and maybe require an idler pulley to stop the belt from flopping under load.

Any bracket kits available? What say you? Of course this is V belt driven
