Delta88 convertable

Hello all, I’m looking for some info on my car. On of the gears in the power seat was missing some teeth, I brought it to a 3D printer and long story short the gear was lost. What I’m wondering is can I use a transmission from any gm or is this part Oldsmobile specific? I can’t seem to find anything for the year, make it model. It’s a 1975 delta88 Royal convertible. Any info would be a great help, my 16 year old daughter and I are trying to restore for my dad whos health is failing and would love to get him back out in this car.

Is this a four way or a six way seat ?
If it is a four way , I have an illustration of a four way unit .
If you can , tell me what number gear that we are talking about . ;
