"Sorry, but it has a very naughty habbit of getting corroded/stuck in the fly-wheel coupling!
Have sometimed been forced to drill a hole in the intermediate housing to unscrew the coupling from the fly-wheel to get it off. Not easy, whatch where You drill so You do not just get into an exhaust chamber!"

I would be afraid to drill a hole in the adapter housing to access coupler bolts. not sure where water passages are. might try a bridge puller on the ball gear, but not promising. no good place to get a purchase. I think I would attempt to pry/wedge adapter housing from block. all options I can think of risk expensive damage. not a good deal there."

is the flywheel bolted to the engine and bolted to the intermediate housing?

"No it's not. How would that work??? Your driveshaft is stuck in the coupler as was said earlier. All you can do is pry and hope it comes before something else, housing?, breaks. You could possibly drill the hole for penetrent oil but it would have to be well placed. Sorry to say but I have been there before and the outcomes have not been nice."
