If you'd settle for an SM420 in a 3/4 ton GMC here is a picture. I assume Chevy's are the same. But mine doesn't "sit" on the frame. The mount at the front of the engine and the 2 mounts on the bellhousing are the only mounting points for the engine/SM420 package. The only "mounting bolts" for the SM-420 are the 4 bolts that hold the transmission to the bellhousing.
