I'm thinking of getting back to the build of my '51 Plymouth straight 6 engine and one thing that put a pause on it was modeling the spark plug connectors. These are those old metal connectors .. made from sheet metal with a 90 degree bend and clamped around the wire with a press fit to the plug. They were all bare metal and were about the wire insulation diameter. I found one photo below.

Some thoughts I had were slitting the plug wire insulation so it would bend to 90 degrees, gluing and painting silver. I think this might be a tough glue job without making some jig.

I do have some rubber spark plug boots that I could just paint silver but these are large compared to the plug wire. Last possibility I will just use there as is. I do have some cast spark plugs I'd like to use and these would cover more of the plug that I want to.

Any thoughts on this would be greatly appreciated.

Wrap end of wire with BMF, bend the wrapped end 90 degrees over a sharp angle. A small piece of styrene rod will do for the spark plug. That aughta do it, aside from weathering.
