So my flatbed was previously welded onto a truck before I bought it. The owner I bought it from cut the spacers off with a plasma cutter, leaving them damaged beyond use. The spacers were just pieces of square tubing that laid sideways across the bottom of the bed. I decided to cut the spacer off and use the center portion for my new spacers, which I welded in lengthwise with the frame. In the end, it does the same job and takes up a little less room. I'm happy with the results, especially since it was my second time welding haha.
Jacking the bed up with camper jacks to work on....little sketchy...the bed is a heavy sucker...
The center section of the old spacer I cut out.
The remainder of the old spacer.
My new spacer welded in where the old one was located.
