Automotive RepairPart Identification & Selection4HighOwner$ implied

A classic car restorer cannot find a distributor cap and rotor that are compatible for a Chevy 235-six distributor conversion, as the rotor spring tab hits a non-conductive center dot in the cap.

Existing replacement parts (cap and rotor) for the Chevy 235 distributor do not physically match, causing no spark. The machinist's instructions claim compatibility, but actual parts fail to work together.
