Weird combination but that "Toro/ tranny" combo has been used for many years to convert things like Corvairs and some Kit cars to a V8 rear engine configuration. If set up right with the right suspension changes its a good combo. I'd have to wonder with that setup taking corners in a tail heavy truck must redefine the term 'thrill ride".
no I get the setup, but to post the ad with no "real" photos of the truck you are selling is just crazy.
as a side note, I have some awsome drawings of the mach 5 that I did. only $10,000 :o
