Getting the brake lines sorted on the 65 meant getting the rear most line on the bottom of the distribution block loose. The regular flare wrench was unable to assist as there's not enough room for the tool there. So I bought the crow's foot flare wrench set from Northern. Verified rotation direction, got it placed and got mad at it. All rewarded with a nice 'pop' and a free moving flare nut that probably has not moved in 54 years. The direction of rotation was actually clockwise to loosen as the flare nut was inserted in the bottom of the block. Just thought I'd share. Well worth the $20. And it's stupid tight in that corner of the engine well.
