Documenting an NOS Hood Pin Lanyard Cable

Initiated by a recently very active SC/Rambler Facebook posting, and some off and on past investigations of what could be made as reproduction, I have created a complete engineering drawing of a NOS hood pin cable.  I purchased this cable as part of an incomplete set of an SC/Rambler NOS Hood Pin Kit in Kenosha 1993.  The reference AMC part number is 3635760 - which is the lynch pin (including cable).  I have decided to call this the "-B" part since we will further document the lynch pin as the 3635760-A part number.

I have documented the original part through non-destructive inspection as the Rev. 0 document revision.  This will serve as documentation evidence of how the factory supplied these parts.  I am now in process of documenting a Rev. 1 version of the drawing to serve as a specification for reproduction and I am currently investigating how close manufacturers can come to providing low volume lanyards to this specification.

The drawing is specifically for SC owner personal use, and I am providing my work here for free to provide the owners with the documentation they need to preserve their cars.  I would appreciate your respect for the use for only that specified purpose.  Contact me for any other use.  Below is the drawing and several photos of an NOS lanyard.
