Ran into a problem with my LS swap on my 87 Suburban.
I don't have the correct fittings to attach my transmission cooler lines with 6an connectors to my radiator. Using an Enytopy radiator by the way.

You'll have to know what size/threads those bungs are..if you don't know contact them to find out what you need,, would be my suggestion.

Most are 1/2-20 straight thread, I've used 6an to 1/2-20 flare fittings with an o-ring.

Qwik is correct in that it is straight 1/2"-20 threads but it is also an inverted flare fitting. you'll need something like this to connect it to an AN fitting.

Whose radiator do you have? Entropy suggest using a 5/16" inverted flare to a 6AN fitting in their radiator.
