Correct kickdown linkage for a '74 Duster?

My previous post was deleted...

So my 1974 Duster (318 2 barrel) is missing the kickdown linkage. I've been researching it and I've seen different linkage types/shapes. Apparently there are different kinds of rods and different shapes of the part that is bolted to the engine block. So, how would I determine which one fits on my car?

Any help would be appreciated.
