Anyone have any ideas on how to replace the sunroof in a 77 f250? well what i have is a 77 f250 4x4 that someone put in a sunroof in. I want it gone. Have kicked around the idea of taking it out and steping the metal and welding in a new panel (Alot of work) but have also looked into the 3M 8115 panel bonding adevshive and have heard very good things about it but $350.00 for the gun to apply it, there has to be a better way. Any ideas?
