HOLY SHIT I FINALLY GOT IT!!!
That was by far the most difficult single task I've ever done. That shit was really really really stuck on there. I'm not some tiny weak dude either. I'm a lean 180lbs and pretty athletic. I shook that shit soooooo hard for hours and nothin. Finally what I think made the difference for me was prying underneath by through the hole left by the inspection plate on the bottom. Then lots of penetrating oil and rotating between prying at 2 terribly obstructed locations, shaking the shit out of it, raising and lowering the trans jack, prying, shaking, etc. The shaking/pulling didn't seem to do anything really until towards the end when the prying had done 80+% of the job.
My clutch/pressure plate actually look better than I expected. Since shortly after I bought the truck about 2 years ago, the clutch started getting super grabby and resisted ANY slipping. At first it was only when cold and/or wet, then eventually got to the point where it was all of the time and recently got really bad.
Really close to the rivets, but not quite
Flywheel lookin HOT!
Pressure plate too.
Thanks for all the help guys.
