We have done tech articles at Webasto before, but this was the first time where we really took advantage of their expertise. We had wanted to install one of its GrandView sunroofs in our Project Sinatra F-150, but its factory sunroof posed a problem, so we looked for another viable candidate. When we came across an '04 Silverado Crew Cab, we thought we were onto something, but its factory headliner was filled with odd contours to fit around the roof's bracing. We were a little skeptical that it was possible to make such a huge sunroof look like a factory install, considering the shape of the headliner. But after watching Ramn transform the truck in one day, we had learned the secret: experience. Ramn has been installing sunroofs for longer than some of us have been alive, so he made it look easy. Check out the install to get a view that's second only to a convertible.

The Crew Cab roof was just long enough to hold the new sunroof. |
The factory headliner contours around the overhead bracing, which looked a lot different by the end of the day. Before anything had been removed, the upholstery and seats were protected with heavy vinyl covers. | 
Ramn began the installation by removing the visors, the overhead console, and all of the trim from the pillars. The headliner was installed at the factory through the windshield, so it had to be folded to fit out of the door. |
Ramn used a putty knife to separate the roof skin and the roof supports, then a sheet of stainless steel protected the roof skin as Ramn used an air chisel to remove the forward-most piece of roof support. | 
The center roof bar was also air-chiseled out. |
