I don't think the Ebay mounts are the right ones, it says they came
off a 1946 which is the G engine. The parts book shows a different number
for the H engine mounts. I have a 1948 F2 and the right mount is 7HC-6037
and the left is 7HC-6038. The part number is cast into my mounts. I don't
know if 1951 is the same.
