DIY Sunroof

I haven't read every single post here so if I repeat something I apologize.  Installing a Sunroof in this vehicle is a pain, but not impossible, I've done a couple.  Webasto sunroof is probably the best one on the market and it has a flexible rubber trim ring to accomodate the ribs in the roof.  If you just want a glass roof, there are Pop-Up sunroofs avaliable that are manually opperated, that would be easy to remove if you wanted to.  They are usually smaller as well so you may not run into problems with the ribs.  Also this would eliminate the need for drian tubes for the inbuilt roof and reduce the chances of leaks. 

If you aren't experienced with this I wouldn't recommend it.  It really isn't a DIY project, especially the inbuilt style.  As for tools, the best is a metal shear, Milwaukee makes a really good model #6805.  I would take an air hammer to cut a hole in the center of the outline for the sunroof, then take the shear and cut off the majority of the metal you are going to remove.  Then go back with a second pass to do the final cut that way you don't have a big piece of metal hanging down causing the shear to bind up, or cause a rough cut edge.  Also tape the exterior of the opening you are going to cut to prevent scratches.

Good luck and definately take pictures this is one we all want to see.
