It wasn't very thick. Maybe 2 inches thick or so. I rebuilt a 79' Lil Red Express about 20 years ago. Someone made new wood slats for me for the sides (the originals were rotted) But they weren't very thick at all. Neither were the originals.
i knew a guy that had a little red. never seen a black. its like my dad said. " i knew a guy that saw a guy, whose brother , that had a cousin, that lived next door to a guy, that knew a guy named Bob that had one."
Well Yes it is almost like the Red"Express", but I believe it cam w/440 Cu" engine while the Red had the 360 Cu" engine. I think the rest of the trucks were the same, except for the engines. I maybe wrong and have confused the Black w/the Warlock but there is info on the internet about all 3 models.
