I got the idea by looking at the angled breather that Metco sells. I figured out how they made the end that engages the valve cover, then duplicated it in mild steel. I turned the part on my lathe then finished the tabs on a Bridgeport using a 3 jaw chuck on a rotary table
I TIG brazed the new part to the stock fill tube, then painted it up nice. I will post a picture of it installed on the car.
