Anyone know what size of fittings go into the rad for the oil and trans cooler? Looking to plug mine. Truck is a 91 Silverado.

this is what i used to plum mine but its a Inverted Flare Size:1/2-20 in
sorry only posted the trans cooler fitting. the oil cooler is a 3/4-18 uns 0-ring. at the radiator
any are you just plugging the holes so dirt doesn't get in? it will be hard to find the oil cooler fitting. i would just use a plastic style cap if so.
