You have one other monkey wrench thrown into the works. The wagons have a hydraulic rear suspension, and the pump is mounted on the head on the wagons. You will have to come up with some sort of way to seal the opening in the head where the pump is mounted.
No, you cannot move the mounts for the engine. Much easier to find the correct driveshaft.
And of course, as noted in several threads lately, you have to change wiring for an extra glowplug, different exhaust connection and system, tranny mount is moved back, but I believe the holes are there, radiator is different I believe, etc.....
There is more, that is just off the top of my fairly empty head.
And, most important, Welcome!
second, Merc = Mercury
