904 La kickdown linkage adjustment

Resurrecting this thread in hopes someone has the answer. I've got a 66 Dart 270 that I've added a Edelbrock D4B intake and an Edelbrock

AVS2 Carburetor #19044 500 CFM​

I'm having trouble finding the right parts for the kickdown linkage. Anyone have a link to what I need?
