*Car '67 valiant signet converting to 68 and up seal/trim n clips. I just put down some new paint on the frame. I bought a '68 n up seal and clips/screws and have a few sets of trim. I'm asking for any advice on the install. I have butyl tape and permatex window sealer. I was thinking I would put the thin butyl tape across the center and then use the sealer or butyl in the seal to pinch weld groove installing the gasket 1st and then stab the windshield into it lower 1st and then use a plastic putty knife to work the seal around the glass from the center n out to both sides top and bottom. I've seen the rope trick...and the knife trick. What's your method? Any measurement for the clip screw holes?
