I bought one of those back in the '90s with the intention of doing just that.. it was big, super heavy, I would have had to fabricate and weld a bunch of frame parts for it. Plus all those extra shift knobs!! The bus is converted to an RV so I don't need 24 speeds, I just need to go highway speed without maxing out the motor all the time :-) Sadly I don't still have the Brownie, which would probably be worth some money to the right truck owner.
