Hi Baron,
I used 3m silicon under the chrome pieces that surround the windshield, no glue. I globbed a large chunk of silicon under each side of the top chrome piece and when it sqwished out, I just wiped it off. They are a very tight fit, but with the added sealer, you will be ensure that you wont have any leaks in the future.
After fitting all of the chrome around the windshield, using chrome screws, you will need to install the top dahs pieces and even the wood. Although I will most likely install my wood after the new windshield is installed. I dont want the wood damaged. Use a extra piece of leather to ensure that the top of the dash is not scratched with the screw from the wood bows.
I hope this helps. If not, please post add'l questions.
Bob
