Well there's a whole new problem i didn't think I'd have... Visually, it looks to me like my holes would be covered by the larger stock style stanchions, but i must admit i have not measured anything, as i don't even have the stock stanchions yet... Dave, can I ask a BIG favor? could you take some close up pics of your windshield, the base where this rubber seal is you speak of, as well and an "across" view from the side to show where your posts are monted in relation to the cowl, and whatever other windshield related pics you could provide? You can e mail them to me directly at joeybsyc@aol.com I'd be SUPER appriciative, as i read elsewhere that your car is a Kilbourne body too, so the setup should be the same. Thanks in advance... if its determined that the post holes won't be covered by stock stanchions I am definitely NOT changing the windshield right now.
