I have the six-page Engineering Parts List for ZL-1 Camaro production. COPOs were initially processed as L78 orders, this listing has all parts added/deducted in production. It shows, for example, the 1115293-coil deducted and replaced by the 1115210.

Plug wires are not listed. No reason to believe anything other than standard production wires were used, as seen in vintage photos of #2 & #3.

Side note, COPO build orders listed the L78 engine. This means the oft-quoted L78 production quantity of 4,889 is overstated. L78 production was 3,823 L72 997 ZL-1 69.
