Removed a complete bowden cable from normal seat from my parts car, which of course did not fit in length, but I made it fitting by cutting the sheats and installing in between a fuel hose with 2 clamps for easy adjustment of perfect length. Works like a charm.
The normal seat gear looks quite strong

But the gears on the E36 and E39 are made of plastic it seems. That is why he is offering replacement gear parts for these models.
I was thinking the Plastic Wheel Gear for the Rear Height Adjust was what must have failed on mine and I didn't see it listed specifically for E34 do you know that another model is compatable? I guess my Six feet 230 pounds was too much....
**UPDATE**
I sent them this image and they informed me they have seen these fail so infrequently they have not aquired the mold to make this gear so I am SOL. I've yet to see one of these seats up for sale.
