There was no welting between the rear fenders and bed side on any of the Chevy Advance Design trucks. Since the fender to bed seam is simply a flat seam the welting is not necessary. The rear fenders were bolted to the assembled bed and it was panted as a unit prior to being installed on the frame.
The front fenders with all their compound curves at the seam were harder to match so they used fender welting to hide the minor mismatch or gaps at the seam.
