Beat Up Bed
FWIW ;
My 1949 original bed is in pretty bad shape , it's been rusted , bent , shot , drilled & split structural welds and burst the stake pockets from getting fully packed with sand then letting it sit and get wet until they rusted and split all the welds , tailgate is all dented up and bowed out about 3/4" from loads shifting back and hitting it . when the original wooden bed support blocks rotted away , it sat on the frame and bent and broke two of the sills , will change those out one of these days...
I ground the rusty edges and had the split seams re-welded , tailgate has pop rivets holding the left seam to-gether untill the next time I decide to re-paint when I'll just have it welded up , unless you're going to make it a show truck , old beds ca be salvaged as they're pretty much just flat sheet metal , if you have acess to and knowledge of how to operate , a sheet metal brake , all the better .
Once all welded and hammered back into shape , sand it as smooth as you can , prime & paint it , will look very good from 10' away .
