"tubman" & "19Fordy" are both correct....IF talking about the U-shaped spacer used to raise the water pump/mount. BUT....there is more to consider in your pictures. Upon more scrutiny, that is a PRE-48 frame when looking at the Ford-like I-beam axle mated with a single, crossways buggy spring. But if looking even closer, that U-shaped spacer is sitting upon what's left of the familiar rubber donut. But the donut is resting upon a BOLT-IN piece of stamped steel. The bolt-in bracket is obviously bolted to the front crossmember....NOTE the depth of the dip in that crossmember.
That chassis almost has to be a PRE-1949 MERCURY chassis, as seen in the picture BELOW.
The Mercurys ALL ('39-'48) had wheelbases 4" longer that like-year Fords. The chassis are similar in construction to Ford chassis, but the engineers had to do some real butt-scratching to make it all work out. The Mercury chassis rails are four inches longer than Ford chassis rails. With that said, BOTH car's dimensions remain the same from the firewall rearward. The four inches on a Mercury chassis has been added between the firewall and the steering box. Note that Mercury steering columns are longer than similar year Fords. The engine and transmission remain in the same relative position with the firewall on BOTH cars. With that fact, the MOTOR MOUNTS on the front crossmember of a Mercury chassis are about four inches too far forward for the water pumps. So Mercury engineers decided to make those extensions which reach back from the position where they're bolted atop the Mercury front crossmember. Look carefully at the third picture above, and you can see them just behind the crossmember where it intersects with frame rail. Also note in that third picture that by moving the front axle forward 4", that the engineering boys at Merc also had to find a way to contain the wishbone ball in the Merc chassis, because it is 4" further forward, tagging along with the front crossmember and axle. They solved that little problem with the 'BOLT-IN' extender, which bolts into the front of the "X" in the frame. It can be seen still attached to the Merc wishbone ball. Coop
NOTE: I just saw your "799-" serial number, which denotes 1947. Ford and Mercury shared SERIALS 1946-1948 because they had identical engines.
