Can an overdrive unit be put on a standard duty truck 3 speed. I measured the box and it is the same as the car where the tail bolts on. I have complete car overdrive setups from bell to tail but the input shaft is shorter and doesn't have the coarse spline for the 11" clutch.

I know I have heard of trucks with the overdrive in them, what do I need to do to use a setup in my 57 F100?

Thanks,

Bill
