Hello!
I found part of a third row seat in the junkyard, so I grabbed it. It is just the seat back part, though, so I thought I might try to DIY the seat bottom. It looks like it just has two bolts that connect to the same bracket as the seat back.
Here is my question:
Does anyone own one of these third row seats that can reply with the dimensions of the seat bottom and bracket part? Also, does anyone have suggestions on how to accomplish this? I was thinking I would create a seat with plywood and foam, and make some metal brackets to bolt onto it.
Thanks in advance.

 

This is what I can offer you!

Good resource, thanks!!
