06 Polaris Ranger Conversion?

Well my engine is blown and I would like to covert to electric. I did some searches and could not find anything. Maybe its not a great project. Not sure. From what I do see, people are converting all kinds of vehicles.. so I know it can be done. Just where do I start? It does have 4WD, and I would like to keep it that way. There was one picture I saw where all the batteries were mounted under the seat (with a little extra fabrication of course. But nothing about which motor or motors?? Any help of where to start or if anyone has ver done this would be great . TIA Cheers. from Arizona
