I’m pretty sure the Republicans don’t have super-delegates. The supposed “Democratic” party does. If the Pubs screw the winner it will be with the rule that requires a candidate to win majorities (not just pluralities) in at least 8 states to be automatically included in the floor vote. If nobody does the party gets to decide whose name(s) is/are placed into contention at the convention.
The GOP does in fact have super delegates.
Interesting article from the WSJ on GOP delegate allocations:

Not as many as they dems, but enough to create havoc.
