WHY are you talking about pulling the oil pump?
I seriously doubt the oil pump caused your problem...unless you have big chunks of crap running through the engine. The starter kick-back is what busted your parts.
Get/make a 'pre-oiling shaft', that's used while the intermediate shaft is out. It has the hex end on it, to fit into the oil pump. If the oil pump turns, via that shaft, with no binding...should be good to go. Don't mistake binding, for when the pump pulls oil into itself. Yep, you'll feel a slight drag, as the pump loads up.
One part I suggest you carefully look over...your starter 'ring gear'! That's the gear, that's fastened onto your clutch pressure plate, that the starter engages to start. A chance a tooth or two might have gotten knocked off.
Later, we need to talk about your TIMING, since that is what probably caused the kick-back. Sure, that's not a positive thing. Possible 'something' broke, causing the lock-up.
Clues...spark plugs out, by hand, see what turns good on the engine, or doesn't.
Distributor points...black spot on the contacts...a possible sign, of a bad condenser.
Easy to find out, by changing it, and see how it acts!! You should always carry a spare with you, anyway.
DAMN! That was a mouthful!
