4 - Its a 3 seat column shift, not a fan, so out with the benchies and put in two bucket seats (no idea where to start looking for these), and then work out something or make something for the middle section
There's a pair of decent looking UTE bucket seats on ebay if you're interested. They're in the Newcastle area.
