'56 F100 Speedometer

[Wiresmith]

Hello All,

I'm in need of guidance. I have a '56 F100 with a stock gauge package. I've installed a T5 transmission from a '95-'97 Mustang with a tag number of 1352-238. I don't know if the speedometer was electronic or analog.

Can anyone point me in the right direction to use this transmission with my stock gauges?

Any help is greatly appreciated,
Mike
