So I got the rear portions completed tonight and got two of them welded together. Please don't mind the wrap on the back side of the tailgate, I never got to go back over it waiting for the bed to be finished before I took that final step.
As you can see in the corner of the pic there is the filler piece for the passenger side wheel tub. I duplicated the drivers side. Hopefully tomorrow I will be able to find some time to throw it on the bench and get it welded up.
Stay tuned!
