The first is getting pretty good steering wheel vibration at about 80mph. Wheel out of balance?, Alignment? The second is my canvas top has pulled loose all along bottom under window. looked as if was only held in place by VHB tape, then tucked under rubber seal? I tried two different grades of tape, both purchased at Lowe's so even though 3M made not be best quality and neither on held in place. is it true that only tape hold it secure? any advice most grateful.
