Got the exhaust system installed. No pictures up near the engine but the exhaust pipes were pretty tight getting turned and over the original-relocated frame cross brace. The rear axle area is also a bit tight given the relocated fuel tank. I will need to relocate my fuel pump to get more clearance but it isn't connected to the engine yet and the flexible line from the tank is easy to replace with a longer section.
Now I need to remove and restore the bed parts for near term. At least I know how they fit together at this point. I'll probably leave the rear bumper on for now just so I am not constantly running into the tail pipes.
