Prinsu has been quite responsive over email. Seems that they might have one for us at some point. I'll inquire further.
Their most recent response:
The feet come with it but that is it not the tracks that it mounts to you would need to source those. Also we do not make one for the 3rd gen 4runner yet so it looks like someone might have just make shifted it to work. Also the 1st gen Tacoma bed is not as wide as the newer Tacoma’s so normally we send shorter cross bars for the 1st gen Tacoma’s. Also we do not have the top rack for that on the website yet so you would need to call in to order that.
Let us know if you have any further questions, if you choose to stick with your initial request then it would be up to you to make it fit properly no guarantee from us sorry.
The original owner of Prinsu (Zach) was working on a 3rd Gen rack as well. That fell through the cracks once Gobi started taking company's to court over how to racks mount to the roof. After discussing options with him he let me know the bed rack would fit a 4runner, and mount the exact same way they mount on the Tacoma's.
The newer Tacoma rack is the one that I have, and I'll pull the actual measurements of it when I get home today. I'll get some additional pictures too so you can see exactly how it mounts.
