[cancobra]

Thanks for the replies and I apolgize for the long time in getting back to this. There was NOT a vibration in the windshield until I removed it for a day with the racing screens on. I reinstalled the windshield and discovered this vabration. It bolts directly to the frame and has ample clearance from the cowl. I have adjusted it up, down, back and forward. I have installed lock washers, removed them, played with torque on the bolts, reoved the bottom frame brace and all to no avail. I have owned 4 of these Auroras and about 7 other Cobras and never had an issue like this. I appreciated the feedback but it looks like time to pull the dash and check for something loose that is somehow connected to the framing.
