Aston Martin AMV8 ignition lead clip

Clip for 2, 3 and 4 8mm ignition leads as fitted to 1970s Aston Martin AMV8s. Copies the original style but with larger holes for the modern 8mm leads as opposed to the older 6.35 and 7mm leads.
Clips onto a rocker cover nut using a shallow taper within the loop part for 7/16" AF nuts.
Drawn in OnShape using a publically accessible file
Might work for other engines/leads, good luck!
