1967-72 Chevy/GMC Truck, Pro Touring Mirrors
The mounting arm should be tilted up slightly and the body line in the body of the mirror should be level with the ground. If you need to tilt the mirror up, just elongate the holes in your door down a little bit. This will rotate the mirror up since the mounting surface is curved.
The turn signal wires and wires for the mirror glass motors are the only wires that I keep. Let me know if you want me to leave the heated glass wires. Just put it in the notes when you check out.
Keep in mind these are Mustang mirrors you are putting on a C10 truck. Visibility in the drivers side mirror is great, and visibility in the passenger side mirror is not good. Same as the factory mirrors. Do not buy these mirrors if you want perfect visibility in the passenger side mirror. These mirrors are for looks only.
