1974 109 wagon w/2.5 ford diesel conversion

Dear Members, I have a 1974 109 Series III Land Rover wagon with a 2.5 ford eurotransit diesel conversion, done in the UK. I am the third USA owner in the USA since it was brought here around 2000. I believe the engine is a 1984 direct injected, no glow plugs from a MK2 transit. I need a source of parts; even though the 2.5 runs well, I will need some preventative maintenance parts. ie. timing belt, with cover gasket, spare water pump, thermostat with gasket, oil pan gasket, valve cover gasket, specific engine service manual, parts manual, etc. This Landy is my daily driver and I believe it should be maintaned and spoiled.
Hope to hear from you all, Regards, Don D. Zappone

a trusy engine that is very torquey, but dunt expect a lot, it will struggle on the slightest incline and milk floats will pass yer
