I would also suggest that you get a car pan in lieu of the truck pan you have.

Boy, I seem to remember that the mounting height of the pads on the late Merc pumps are different than the truck pumps (higher in relation to the vehicle). I know because my test stand has the analogs of the '40-'48 Ford mounting geometry (I have used it to test a truck-pumped 8BA, as well as an Olds and a Hemi with Hurst mounts). When I went to mount the '51 Merc that eventually ended up in my '51 Ford, I had to make the spacers I mentioned ealier to bring it up to the correct height (it had the Merc pumps).

Also, why wouldn't the truck pan work? I have one and it seems to be the same outline as the Merc pan. I know the "cleanout" is prone to leaks, but given the rarity and price of Merc pans (per Coop), I'd use it if it fit.

It might be a good idea for the O/P to sight through the crank hole in the grille and see just where the crank bolt head is in relation to it. In the alternative, stick a dowel or welding rod through the hole and see where it ends up.
