Soon after the drag season started in 1964, I concluded I needed a deep-sump pan. So I built one by adding the sump from a 'boneyard' pan. I cut a hole in the bottom of the original pan, large enough to pass the bell on the pick-up, and added a piece of half-inch electrical thinwall in the middle of the vertical part of the pick-up. I overlapped on both ends and notched to reduce the diameter. Brazed it all back together. Worked just fine, and in those far-away days, I don't think I spent five dollars on the whole project.
