Anyone know any specs on the GMC General used in Smokey and the Bandit 2?? Such as engine,wheelbase,sleeper size?? I am assuming the engine is a 8v71 or 6v71? And from what is ee in pictures it looks to be a 50 inch sleeper? It definaely is to skinny to be a 60 or more. I have a chevy bison kit i wanna use for this just need to swap out the grille.
