Hey guys I current have my bed off my truck and am needing to replace the cross sills. The old ones are rusted away, I know that I can just use some box tubing but I would rather use ready made pieces anyone dealt with this before???

 

I am going to be doing this this summer, ebay sells replacement supports but they are around $500. Personally I would just replace them with the square tubing because you can easily remove them if they ever need to be changed again. Its all personal opinion but I think the box tubing is the way to go.
