No turning back

My work will be done in spurts since I have to work 12 hr shifts each week. I plan on getting the metal tacked on this weekend. I am going to use a 6" pvc pipe to roll the metal for the bottom tuck. The only issue I'm having is bumper mounts. If I roll and install the bottom section It may be difficult to install the mounts. I will probably use the existing mounting holes with modified brackets. The old piece had cutouts for the mounts so I may just do that after it is installed.
