You can use a 3/16 brake line threaded fitting. You can go to nappa get a 1 foot piece of brake like that is flared on both ends they come with two fittings. Weld them on and your good to go. Might as well get two new ferrels while you are there. I learened that from Digitron Direct. He gave me the option to buy them for $20 bucks or go to nappa and get them for $2.
