oldieoldie, the tube nut is standard 1/2" inverted flare, the street elbow is 1/2" inverted flare on the female side and if I remember correctly it is 1/4" male pipe thread on the other end, it might be 3/8" male pipe. The street elbow looks ok, the tube nut will be available at your local parts store, you might be able to buy a 1/2"x12" tube with the nuts already on it.
