I've been reading about the 4200 with interest with an eye towards putting one into a 60-63 Ranchero or Locost. Then the idea struck me. Could one keep the Trailblazer awd configuration and put it into something like the Ranchero? It'd undoubtedly require me to extend the current limits of my skill set, but potentially be a heck of an end result. What major obstacles should I expect to encounter beyond the obvious one of making a RWD vehicle drive the front wheels?
