Hi RAC1812,
Looks like you have some solid leads. If the members of the MLU forum can't help, I'm not sure who else could.
One other resource that you could try is these guys:
wildenberg partsI don't think that they deal in CMP parts, however they are a third-generation surplus military vehicle parts source, and have been selling parts in NL for 50 years. They have always been extremely helpful to me. You could try shooting them an email and ask them if they know of any CMP parts sources.
Best Regards....
