55.2-59 58-59 fleetside bed braces

[57FleetsideC4]

Hi, I have another question. I have searching around for the 4 bed brace that go from the frame to the bed at the sides. I only see ones for 60-66 fleetside trucks and wonder if they might work. I had a link to them but the link is no longer good. Does anyone have a source or know if the 60-66 would would work? I really appreciate all the help with these smaller items. Trying to collect as much as possible so when it goes back together there will be no hold ups. Steve
