Transmission line fitting size

I need to order some transmission line and some compression fittings for Brutus.  Does anybody know what  size the threads are that go into the radiator.  

This thread has some good data in it : http://forum.garysgaragemahal.com/C6-plumbing-td57026.html

I recall Angelo was interested in the transmission end though so focus is likely there.

Do you have the adapters that Ford used?

Thanks for that, very interesting read.   Yes i have the original adaptors.  The line broke right after the fitting.  i have it rigged with a hose for now.

Well the amazon fairy brought me my new flareing tool and it is going right back.  Never before have i seen a tool hack up a piece of tubing like this one does, but i guess you get what you pay for.  In pricing a new tool, i decided to go ahead and get the prebent fitted lines from LMC, they are only 54 bucks for the pair and i think this is the better way to go since the new flareing tool cost more then the lines themselves.
