Definitely single rod going from the bellcrank at the back of the intake to the tranny.
Johnny over at 71superbee.com will definitely have some information if you can't get the pictures here.

YearOne sells it too.. A bit pricey for the complete kit. The carb rod and bellcrank could probably be used from a 4bbl car along with the kickdown tranny lever down at the bottom. The unique piece is the actual rod. A 4bbl version will hit the firewall. I have had a 6bbl setup on my former '71 Charger R/T and know first hand a 4bbl rod won't work.

Hope this helps...
Now that I think about it, I have a 6bbl single rod up in the attic. I"ll take a picture later on today if you don't get one via a reply
