CRD Diesel's

I've been toying with the idea of putting a diesel into an A body for some time. Over here in the states though we don't have a lot of choices for small diesels since very few passenger cars came with them. The engine would have to come from a utility type truck or a tractor. None of which sound like viable options to me. Hooking up a modern O/D trans either manual or automatic being the most challanging part.
