This is a 1983 Euro 300D NA engine in a W123 1983 240D. The M Pump looks different. I will get some pictures shortly. I will also try to re-post some pictures I got from other forum members of what this looks like. And yes, this is a unique or particular application. The MW pump set won't work.

Thanks guys and I hope to score one shortly since I am getting my donor car this Saturday. The Sleeper Part Deux !
