Kickdown linkage help

The kick down linkage for a slant is very simple its only 3 or 4 pieces. In your photo you have the shifter linkage, that piece attaches to the frame rail and a bracket on the transmission. A service manual will show you in detail how everything goes together. I have the complete kickdown for a '72 dart that I swapped a V8 into, you can have everything from carb to trans for $20 if you need it.
