short engine mounts

[Rob Dyba]

I have installed a flathead into my LP2 and am having trouble getting the water pump outlets to line up with the radiator. All the pumps I have have the same height lugs as each other, so I am wondering if my mount is the correct type. Currently the outlets on the water pump are about 25mm lowwer than the radiator outlets, the engine mounts I got from Mac's auto parts to suit a Mercury, having been told they were the same. Can anyone assist or at least quote the height of an original mount?
