Hey Matt,

If you grab the complete mounts, sump and pickup from L series 720 ute it should all fall in place, does with the later 620 ball joint chassis, pretty sure the early one is the same.

Use a short gearbox and you can keep the factory tailshaft.

Might need to trim back the rad support panel where the radiator bolts in, or use a smaller radiator shifted forward, or loose the engine fan and run a thermo.
