power seat

Hi all- I'm looking for the top (round) gear that attaches to the worm gear in the power actuator motor assembly. I don't believe this is a part that is reproduced so if anyone has an old junk assembly and would like to sell me the gear only it would be most appreciated. I'm in the DFW area...

Tilt and raise/lower works but seat doesn’t move in forward direction. Pretty sure it’s all the way to the reverse stop but assuming that control doesn’t work in reverse as well. Could this just be the switch or is it more complicated than that?o
