Ok! I had played with the top cover last nite and got neutral for 1 2 3 4 but not rev. Moved the rear gear to the position in the picture and spun the input ,holding the output the front turns rear stays free so we have neutral. There is a drag on the gears probably crud from 63 . good soak coming wish i could put a motor on the shaft and spin it to free it up. The ratchet is a little underpowered.
