Tomctomc,
I installed mine from Classic Parts on my 55.2 and I found that the thing was just barely big enough to cover the roof. If I took off the rubber moulding you would see a big gap around the entire thing. Did you have the same problem?
Also, I used 3M Super 77 and it sagged after a day in the sun. Any other adhesives that work better out there since I have to redo it?
