I saw an ad for an outfit in Cincinnati selling all kinds of mini truck parts. Along with the usual stuff, he also listed something called a "front end conversion". I called the number but got some forein guy that I couldn't understand. Is this a way to convert a 2wd to 4wd? Is such a kit available otherwise? I've seen quite a few 2wd truck reasonably priced and if not too expensive, I would consider converting it to 4wd.
