Does anybody know where I can get repair panels for a styleside bed? I need the end cap panels where the tail lamps mount. Also need a tailgate. Thanks

 

I don't know of anyone who makes the tail light panels for that bed. I had mine (58 F100) repaired. You could cut a good pair from another bed (or use the whole bed if it's good). I think the tailgate from a similar era stepside is the same (up to '78?). I put a brand new set of tailgate chains from a '78 stepside on my truck, they fit and looked perfect.

 

there is a company called MAR-K www.mar-k.com i'd try there to start with

 

Around here there's a guy who advertises that he hauls trailer-loads of parts north from warm dry places on a regular basis. Someone like that might be able to fetch you a bed or parts of one from a rust-free truck.
Otherwise... my friend fabbed up his own replacement lower sections. Grab some sheetmetal and a ballpeen hammer and a tree stump and you may be surprised (or just appalled) by what you can make.
