I recently acquired a second gen 4runner that is already chopped. I would like to get my hands on something (pick up rear cab or 4runner rear cab) to seal it off. But for the mean time, do you think something like this cab partition would work? http://www.killertoytops.com/?q=node/20

 

something like what you found would work just not that particular model. A Boat Top shop or upohlshry (sp?) shop could probably make something for you...

 

What about a izuzu rodeo top. They look like they would fit with some minor work.

 

Grats on your runner!

Post some pics so it will give us a better Idea of what can be done or where you can go.
