the only gotcha I am aware of is the availability of sheetmetal, if you have a complete bed and rear fenders you are ahead of the game. these "war years" trucks got used more than any other because production stopped 42-45 (there were a few of each 42 and 45) so farmers just cobbled them together and kept them going until the AD trucks came out in 47. so most 41 and 46 either got used to scrap or abused until the new trucks came around.
