Fuel Line Clip Question

[pjmoreland]

My '68 C10 has 5/16 hard fuel lines (307 engine). The line that runs along the frame is held with the regular clips everywhere except at the very front end up by the fuel pump. At that location there is a large slotted hole in the frame and there is a piece of sheet metal bent around the fuel line, stuffed through the hole, and bent on the outside of the frame to keep it in place. It does not appear to be an original factory clip because the ends appear to have been cut with tin snips and the cuts are crooked. What did the OEM clip look like in this location?
