I have several factory 8-Tracks, some with MPX some not and an MPX. Wires have been cut. Does anyone have wire to speaker details?

As a side note does anyone have absolute fact about these units. I've seen many combinations over the years as well as the brochures. This web site only details the part numbers which is great but it seems that some of the combination possibilities cannot be substantiated. I'm also already aware of the AM/FM details.

Thanks,

Rick
