Here is a link for kick down linkages, not sure if this is what it is..... Lot of wading through pictures. Did car have aftermarket kickdown? Good luck, not my idea of a way to spend a weekend. Mopar Kickdown Linkage - Bing images
I think you nailed it. The car has the original kick down. Too dam cold here in Canada to take a look right now but supposed to warm up this week. Thank you for you time and effort.
