The wife ran off to Atlanta to take care of the new grandkid so I managed a double header today.
End caps on bed are pretty bad so I decided not to use them as a reference point. I decided to mount the bumper 2.5" behind the bed beam since it is straight. One day the bed end caps will be straight and they will line up with the back of the bumper.
Screwed a couple of boards together to create the 2" spacer. Clamped the spacer to the beam and pushed the bumper tight against it for the consistent spacing. Note that once I tacked the angles that bumper bolts through, the lateral position of the bumper was fixed. All I had to worry about was vertical positioning and level.
The assembly rolled away from truck. Everything tacked but no outriggers to outside bumper bolts.
Cut and drilled a tab for the bumper. Fabricated the outriggers out of some galvanized metal I had.
Trimmed all the excess metal plates and got 80% of the welding complete. Decided to put it back on the truck to see if any of the pieces wandered off with the welding I had done.
