Swapping radiator problems 1984 Silverado

[HotRodScottsdale]

Got a question for the group. I'm in the middle of swapping on parts from a 83 gmc c2500 I stripped a few years ago and putting them on my Chevy k2500 and just noticed now the radiator I'm putting in the Chevy from GMC had a different heat hose routing system. My Chevy has the hoses from water pump to heater core to intake and the radiator I'm putting in is ment to have heater hose from radiator to heater core to intake. My question is what should I do with the hole for the heater core now since my engine wont require me to use it and if I have to plug it what's the best method, it is not a threaded hole just a hose clamp one.
