440 6 pack kickdown linkage question

I have a factory-mated 440 and 727 with 4-barrel kickdown linkage. I have a 1975 Plymouth Valiant, and I have a 6-pack setup complete (Sorry, six-barrel).

If I want to keep a factory-style kick-down linkage, is there a linkage for the 6 barrel that will work with the A-body chassis?
Yes I know Lokar Cables exist. I'm looking for factory-style if possible.
Thank you
