It may be a little easier if you unbolt the 3 pin driver from the flywheel cup (sometimes this helps and other times not)
I think I have done that, still attached.
it may also help to pull the pin out of the clutch release lever/hanger.
Are these the pins you speak of?

You need to remove the anti rattle springs shown in your pic. They're gonna hold your clutch drive disc to the 3 pin driver. That could be what's holding you up. If you pulled really hard they'd probably fly off, but they may damage the clutch drive disc. The clutch release lever/hanger is on the right in your pic, the pin is at the top of it. Your clutch drive shaft passes through it, if that helps. Good luck!
