Got an idea.....

Yeah, the spur and diff will work together, but what about the diff and 9.5 chassis? It looks as though it's about the same size, and I don't think that Ofna would change the bearing sizes on the diff from car to car, so I'm pretty darn sure it'd work. Problem is, I can't even afford a single spur and that cheap diff......darn this poorness!!! :D
