column shift linkage

I have a '72 Scamp, 383, 727, With T.T.I. headers. I would like very much like to retain the column shift function so that Mrs. can drive. Scamp had 318-2, 904. I am seeking the linkage that goes from the column to the shift arm of the 727. I think there is cross shaft that goes from tranny to frame rail and a couple of shafts that tie it all together. I also have Schumacher mounts and it says that mods are needed. I am at 032 zip, thank you, 383Scampman O:)
