Which spedo-gear?
68-442, with 391posi rear diff, Muncie trans.
Which speedometer gear should I use? I see different colors associated with different gear count. I'm not sure how to decipher the chart in the assembly manual.
Help please and thanks

This question cannot be answered without knowing the tire diameter (NOT the wheel diameter).

This is from 1970, but should work. I found the specs on the F78 to be what you're looking for so that line should work, BUT you will have to find the correct adapter to make it work.
This place has the adapters.
