You're asking yourself the wrong question. You currently have the nuts, so your question should be what is the maximum bet size that I think villain will call.
In any event, it depends on the fish. How often does he limp? If he limps broadways, he probably has 2-pair - just shove and stack him. If he doesn't limp often, then he probably has a flush draw. Bet pot and fold if the flush draw completes on the river and he shoves into you.
I'm not sure why you would call a shove if a club comes on the river. A tiny-bet/call, tiny-bet/call, donk shove line when the draw completes on the river is pretty much always the draw getting there and never a bluff at these stakes. If this turns out to be the 2% of time when we get bluffed, then good for him.
