When updating electrical systems for my 67/72 trucks, I often scan the parts available for the next decade and modify accordingly.
On the Flying Coil set up -- as I was unable to source the OEM Remote Coil mount and its stud-head bolts, (forged from purest unobtainium), we adapted, improvised and overcame with cutting down some industrial structural extrusion into a steel arm to hold the coil.
Works fine, should last a long time.

They are available aftermarket for 8-cyl. I'm probably going to use one.
