Another picture
Dave,
Another thing to note in this picture, I have seen two different top tanks. Notice that your top tank hose connection does not line up with the cut out on your fan shroud? I have a picture of two different '67 top tanks....one more lateral and the other more medial. The more medial/middle one lines up with the fan shroud cut out.
You can see if Jeff's picture, the hose is more to the middle and lines up with the FoMoCo. Your hose is to the left of the FoMoCo casting. (closer to the fender)
