Trans Cooler Line Fitting Size

[71meangreenc10]

Anyone know off hand what the thread size for the trans cooler lines going into the radiator is? Is it a fine thread or pipe thread?

Thanks

I believe it is 3/8 flare. I know it's flare. You can get the pre made lines a any auto parts store, in the brake line area.

5/16" inverted flare nut.

Where could I find a tap and die to clean one up (also need to fix the radiator threads)???

I have had to get a couple of 5/16 inverted flare nuts or plugs from the local auto parts store. used my die grinder with a cut off disc to cut a few reliefs across the threads at a slight angle (so it looks like a tap) and threaded it into the holes. this worked to clean up the threads that would not let my lines start.
