Larry,
I'm not sure, but I think the linkage for that transmission is the same as my 66. I will post some photos later today if you don't get it answered before then.
EDIT:
OK, here are some photos. I'm assuming your linkage is the same as my 65 and 66 trucks.
Linkage Rods Rod A mounts on the rear position of the transmission and the front position of the steering column.
