If Rani's 68 parts don't work, I know of a 66 Valiant Signet with the automatic linkage in it too....I never messed with the auto stuff in these early-a cars. The car pictured is one I want to buy soon to part out, it aslo has the steering column in it too, I think the 1966 A-Body auto column shift is a 1-year only item too.
Would you go auto on floor or column Mike?
