Okay I measured the axle the best I could and came up with 37.5 inches for the missing axle which is the same as the left one but the gears don't slide in and link up when I slide the left axle in the right side it sticks out about 2.75 inches or so.
The flange is 4.75inches wide with 8 bolt holes that are 5/8th inch wide and the bolts are 1/2 inch. And there are 16 teeth in the left side axle.
