I just went through this with my 70 skylark. The only mirrors that will work are the 70-72 Skylark or Cutlass mirrors. All others are differnt and will lean too far inward. Mirrors from other models will mount up but will not look right.
$150.00 per pair plus shipping without gaskets. You will need to get the gaskets from Duane. I assume since you are going to repaint them you do not care about the original color. If you care about the orginal color let me know. I have a good selection.
