I have this gm three speed and I don't know what it is. The inspection plate is on the top. It has 10 spline shaft. I haven't got the numbers off of it yet, it was given to me. I think it might have come from a truck. I'm curios as to what the gears are. It looks like it's in near new condition. Do you think that 3rd gear is a 1:1 ratio?

I imagine it is 1:1, how many lines are on the input shaft?
