L98 engine ignition wire holders

These were made for the C4 Corvette but may work with 3rd gen Camaros with the same engine. The designs were based on the original parts (from which I could not find exact references) and from the DORMAN 40295 spark plug wire retainers.
There is a 2- and a 4-wire version. I added reinforcement ribs not present in the original parts, but those may not be necessary in the long run.
Original parts were made of ABS.
