The chrome definately goes in before you install the window. You will nedd your very best friend to hold it all together while you are inside installing the bead. Set your chrome and get an 1/8 ' diameter nylon cord. shove it in the grove all the way around and let 8 inches hang out at the ends. Coat the rubber with vegtable oil generous and place it against the opening. While your friend is holding and pushing slightly on the windshield, pull the cords each direction from center, and around the windshield until the cord is completely removed. This will set the rubber without tweaking the glass and blowing it up. Cheers

I would be doing it before I install the windshield, what holds the chrome in is the windshield, have you done one before? cause there is a right way and a very wrong way..I have done a few and have paid the price to have to buy a second one...and now days they aint cheap, I recommend you call someone that will come to your home and install it if your not sure...the most I have paid is 100 bucks ...
