I think I understand the idea of swapping the input, providing one has the dodge unit and want to bolt it to a GM bell and keep the speedo. I have an early (93) Chevy nv4500 with the speedo tone ring for VSS.

I am wondering if the inner/outer diameter of the tone ring and the inner/outer diameter of the Dodge speedo gear are close enough to swap even if some editing of the parts are involved. Or perhaps it is easier to swap the output shaft with the tone ring on it, to the dodge 2WD output shaft for the purpose of maintaining a mechanical speedo.

Since I do not have a Dodge trans to compare the two, I'm just assuming that the speedo gear (Dodge) is on the shaft in much the same position as the Chevy tone ring.

I would like to make this work because with all the reading and searching I have done, I've yet to see someone even suggest it. If I can edit the part diameters to fit successfully (preferably the speedo gear), that might be info worth sharing.
