Thank you Mike, for the feedback and pics (beautiful car!). The beltline of my car looks almost identical to yours (except mine has no paint right now) and I knew the top fabric overlapped the tackstrip but when i saw this nickle sized hole in the recessed where the tackstrip sits, it made me wonder if it were there for tooling, or drain, or whatever. You and Dick (above) are pretty much saying the same thing. Im thinking I will just make sure it is sealed and install everything as you have. Thanks again for the feedback! Much appreciated!
Phil
