I have a '62 BT-7 and need to replace the top dash pad. Question: Is it necessary to remove the windshield (by that I mean the whole frame; posts and glass, not the actual glass alone, of course) to do a decent job of replacing the dash top? I ask because I thought it'd be an easy job of a few bolts but it looks now like there's at least one hidden/hard-to-reach bolt securing the windshield frame to the shroud, near the middle of the frame. No idea how to get at it without pulling the glass. I must be missing something. Any tips?
