There is nothing too it. However, you need to have a plan on what to do with the roof line and cut lines. I am thinking about taking so 1/2 conduit pipe and finishing the cut line with it. Anyway, good luck with whatever you decide.
I am going for the rhyno lining once I have everything done. I still need to relocate the brake control to the driverside firewall. It is not a daily driver - yet.
