I've seen the canvas top on a truck in the city next to mine. I might knock on the owners door and ask him where he got it.
I've seen another on an old ford F1 as well.
I did a search in Carson and American Camper Shell pops up. I'll give them a call.
found one on craigslist mounted on a '54 bed but it memory serves
me, that bed has flat side rails instead of the angled rails on
'47-'53. I still might drive by and check it out though.
I read that the '54 stepside bed was produced till the late '80's with different fenders depending on the year of the truck.
