attached is a pix oi a 8BA engine in a '37 pickup using truck pumps and the '49-50 Merc U shaped mount extensions...
The bolt holes on the 49-50 Merc and truck pumps won't line up with the stock EFV8 mounts, the bolt holes in the Merc U shaped adapters are offset, two bolts are required, one through the frame mount, another through the U and water pump.
