ok, i was under the 53 a couple days ago and upon closeer inspection i have found that the four speed in the truck isnt an sm420 like i assumed would be,
what else could it have been in 53 in the 6400 16,000GVW trucks ? it is cast iron case and it has at least one PTO because its a grain dump truck.
are no marking on the shift knob.

thanks for anything
