BTW, prototype plastic molded parts are quite cheap these days. If it were me, I'd contact Gamiviti, but if they don't want to reverse engineer the gear, then I would do a short run of molded parts and sell them here. I wouldn't make any money on it, as this thread shows that this isn't as big of a problem as it is with the LC.

Since I replaced the gear in 2015 I tell everyone to not adjust the seats unless they have to! And as I'm the only one that drives the rig, the driver's seat very rarely gets moved.

I was going to 3D print it in the next day or so to test. My idea was once I was sure my gear worked to actually print a female mold that the metal shaft fit into and cast the gear out of epoxy with a little bit of chopped glass in it.

If you have a contact to do a run I’d consider that route

Making a few tweaks and crossing my fingers it's perfect.

That being said if anyone needs any replaced, let me know. I'll probably put together a kit of 2 gears with instructions and post it up (I figured $30 shipped was a fair price to cover my costs).

How do I manually adjust seats w/o power? I have a 99 4Runner Limited and I just want to be able to access the 4 bolts.
