Today's update... Due to my paranoia about the rear frame measurments, I put the bed back on and made sure the gap was straight to the cab. Then I made some dual purpose gussets. They not only gusset the step in the frame, but they will be my lower mounts for the lower links. I tacked the outer plates on while the bed was still on, just to make sure. I have dinner plans for the next 2 nights, so work on the truck will be minimal. Oh yeah, some parts came in. 5 lug hubs from layinrockers, and all new ball joints and tie rod ends. Here is the pics....
Plates for the inside of the frame.
