It's difficult, but possible to get the pressure plate bolts out without turning the engine. There's a small window at the top of the bellhousing covered by a sheet metal plate. With a little ingenuity and some unprintable language, it's usually possible to coax the bolts out with a universal socket and the right combination of a flex-head ratchet and some extensions. You can also soak the cylinders in some penetrating oil such as PB Blaster or KROIL and use the chisel end of a shepherd's crook wrecking bar on the flywheel teeth to get the crankshaft moving.

Patience is the operative word here. Try removing the distributor, starter, fuel pump, road draft tube, etc. so the engine can be laid over on a forklift pallet for access to the flywheel teeth. Good luck!
