when i replaced the 318/727 combo in my 74 dodge 4x4 pickup with a 440/727, all the linkage was re-used from the column shifter.
with that said, i'm guessing [?] or ASSuming [] small block 727 passenger car 727 linkage will work with big block 727 transmissions as well.
however, i have been [way] wrong in the past, and i will be [way] wrong in the future.
your mileage will vary.
