Reply to Rob T about mounting pump on the bottom of the engine

With a thru bolt mounting plate and thru bolt pump flanges (Aviaid p/n 76). The plate could be mounted on stand offs on the oil pan studs / bolts and some available thread holes in the block not needed. Allowing it hovering (or hanging rather) over the pan allowing you to mount the pump to the bottom the block.
