[1960HDGMC]

Hello, I would like to know if GMC used the same shifter knobs, shifter Lever and Turn Signal Knob and Lever on automatic and Manual Columns each year 60-66. I am seeing what I call a Tulip shaped knob in the literature for the 1960 Hydra-Glide Auto trans. The Inline Six Shifter Knob looks to be a different Tulip Shaped Knob, in the literature. Were there two different, but similar, knobs used in 1960? Did GMC use the Tulip knobs for either shifter or Turn Signal in any of the 60-66 trucks? I have a Tulip Turn Signal Knob and threaded arm, but I do not remember what it came from. I do not recall seeing the Tulip Shifter Knob on any GMC trucks From 60-66 that I have seen. GMC did the automatic Hydra-Glide trans starting in 1960. What would the Shifter Knobs and Lever, and Turn Signal Arm and Lever look like for this 1960 !002 with Auto Trans? I have added some picture from the 1960 Maintenance Manual that show the knobs in question. Thanks for any help, Greg Mead
