Dana 3sp transmission - Model identification

[Mike K.]

Hello, I'm working on a 1970's, Dana three speed transmission. Is there anyway to tell which of the four models I have? Is it just the crank arm length and cable length that differs? I'm trying to figure out if the one I have is for a 26" bike. Cable length dosn't matter on this bike. I'm making a custom "suicide" shifter with new cables. Thanks!!!

How did your project turn out, I think is just cable length that's the difference
