The auto pact of years ago forced the auto industry to build some creative vehicles. Beaumonts, Acadians, Frontenacs, Meteors, and today's pick: Maple Leaf . 1937 Chev 1/2 ton with 36 Maple Leaf grille shell.
I don't think I would follow the current builders idea of the Colorado 4x4 frame -
I would go low- maybe source a stock frame - I have had them before- or maybe gasser syle with a straight axle.
292 6 cylinder or built up small block ... It would make a cool ride and definitely not very common.
