When I was in high school and toolin' around in my '54, a classmate had a '49 GMC that he got with a utility/tool box bed. He took off the bed, made a flat bed out of wood and put on some inexpensive trailer fenders that he got from J.C. Whitney. It's an alternative if you need fenders or mudflaps to be legal.
If I were you, I'd go to an inspection station to get the best info. I once got a ticket for "causing" someone to rearend me in my '54 because it had only the one original tail/stoplight. I got out of the ticket but still had to go to traffic court to take care of it and missed a half a day of work! The thing that I took for granted, knowing the one taillight was original equipment, thus legal, was the hardest thing to prove to the court judge, back then in 1979. I got a signed statement from the former owner of an old Chevrolet dealership that my truck originally had only one taillight. There weren't any Stovebolt Websites or much resto info on 50's Chevy trucks then.
