The cabs are the same on all the '46 trucks.. so are the hoods. That means the cab and hood from a '46 1/2 ton will fit on everything up to a 2 ton.
Hoods are the same way.. I swapped the hood off my '46 2 ton with the one on my 1/2 ton.. perfect fit. Grills outta be interchangable, too.
The only thing that I think would be different is the front fenders.. the 1.5 and 2 ton trucks have bigger fenders to accomidate the bigger tires.. i'm not really sure what size tires they put on a 1 ton '46.
Headlight buckets are all the same from 1/2 to 2 ton.
As far as what the original tail LIGHT (there was only one stock) would have looked like, it would have been on the drivers side, and had a T shaped bracket hanging below it for the licence plate to attach.
