As I imagined. I just needed to make sure that the other M110's didn't have a different area where the flywheel bolted up and what not. I wanted to make sure that nothing changed. So what car do you think I could pull one of these out of?
The biggest complication IMO is finding the set of pedals from a w114/115 car. Also getting the right drive shaft length, and the shifter linkages to fit a w114/115 car. Getting a manual trans setup from a w115 makes all that a lot simpler.
I will admit that I do not know if the rear of the 240d sits at exactly the same location as the rear of the m110 engine, but I would imagine that MB would make the rear of the engines sit in the same location to maximize parts interchange. Keep in mind that the 240d, 300d, m110, m130 all used the same flange, meaning the same transmissions could bolt to all of them. So I am thinking MB would make the back of the engines all sit in the same location. That means the front drive shaft I have should probably bolt right in. This is all probably a pretty bolt-on application that I have.
I have been trying to convince the T5 fintail guy to take the 4-speed transmission to just get rolling on his project, but he really wants overdrive with his 4.08 rear end. I don't blame him. But if there IS some difference in the flywheel, them maybe I can get that trans and flywheel off that m110 setup... But would the euro 185hp have a different flywheel than a ~130hp North American m110 would have?
Is the 1973 280 going to keep the original engine? Or might you be swapping to a euro spec m110? (All that is assuming the car is a North American m110.)
