Mike I can do a verbal but all 10 of mine are converted.was thinking about another one but financial restrictions are in effect At this moment!
I can do it in about an hour start to finish! You only need a dremel with a milling cutter to remove the cast hatch on the roof!
Then you cut the sheet lead to fit. Paint the new roof flat black or Tuscan red and add a new hatch. I can send photos to you if interested!
i'd like to see a picture or two of that myself.
