Question Transmission/Radiator Fittings

Alright guys. Quick and hopefully simple question for you- What are the sizes of the input/output on the TH350 transmission, and also my radiator (it's a 1975 Chevrolet Silverado C20 Camper special)?

The reason I ask is I'm looking to buy adapters to run 6an hose instead of the steel ones.

Thanks in advance guys

Re: Transmission/Radiator Fittings

Radiator fittings are probably 5/16" inverted flare with a 1/2" hex head. If so, that means the thread size is 1/2"-20. So, you'll need adapters like Russell #640330.
