Whatever it is, it's WAY cool! I see a transmission there, but what is the engine gonna be?

 

I pretty much built the whole thing. Rear of the tub is 26-27 T touring back, cowl is from a 29 A fordor but a lot of mods to it. I built the doors and the part under them that connects the front and back. The bed is late T with about 20 inches cut out. Grill is 34 or 35 chevy with 4" sectioned out. Tranny on the floor is a T-5 that's going in behind the 63 Ford 260 engine. Front axle is narrowed Econoline, rear is 58 Ford car 9"

 

Now that is quite a piece of work there. Don't think you'd have any problem making those two trucks into one nice big window shortbed.
