This may help you a bit. The Sno-way plow (as mentioned in the link) website has a something listed for 86-02 4Runners. With the redesign and all they may not have gotten around to fitting one up yet. Also possible is that the haven't updated the website. If anything it may even be possible to do a minor mod and get one to fit (just a guess on my part).
I'd say best bet it to call up the company, or any company, and ask what your options are.
