Matthew, just an FYI, that is not the factory setup on your 123. A previous owner added the rag joint to the engine end. There should be a coupler there like this one bolted to the engine flywheel:
Here's how the drive shaft is supposed to connect to the engine coupler.
You may have to remove the 4 bolts holding the engine in place in order to slide it forward to get enough clearance to remove that setup from the engine end.
