The tranny cooler ports in the radiator on my '82 K3500 are the usual 5/16" tube size with 1/2" x 20 threads..
As for the oil cooler lines ,I have never attempted to remove them from the radiator for fear they will tear out the tank instead of un-screwing..

I know the block ports for oil cooler hoses on the 6.2 block are 3/8" NPT ,but I don't know what size or thread the radiator end is..
