I lowered the tranny and without loosening the big nut at the rear end of the front driveshaft I was able to slide it back about an inch or two but the shaft wont quite disengage from the tranny. Is there anybody thats replaced the front driveshaft on a 1989 300se that has some insight? I can see that theres a centering pin between the driveshaft and the tranny from the repair manual which is pretty vague. Tommorrow I will cut the old flex disc off and see if that pin is floating - unless somebody else has a better idea.
