Oh ok thanks for the explanation. I know worrying about how it sounds is pointless but I'm running short on funds so to keep this project going, and keep me from getting bored, I want to do all the little things that'll make it cooler but don't cost much.
I got the bolt pattern of the Ranger's bell housing mesured so I'll draw up the adapter as soon as I get back from the roofing job I'm on. I'll try ad see if a shop teacher a friend and I had would be willing to cut the adapter out of wood on his CNC router to check it fits. I'd ask my friend do it after work but they don't like running wood because it makes the coolant gross.
When I compare the weights of the Mercedes and Ranger flywheels do I need to take into account how much the full torque converter weighs? I'm assuming so. If that's the case it looks like I'll luck out and be able to use an adapter to join both flywheels to the engine.
