Many GM A-Bodies have this common rust problem and while repairing a 1970 Chevelle I put together an easy-to-follow step by step process to fabricate window channels and sail panel corner patches. With some basic tools and patience you can repair this area that commercially-available patch panels aren't currently available for. It is available as a FREE PDF download from my website - you can get it by CLICKING HERE, or you can access it by going to my website Belden Speed & Engineering and navigating to the "Technical Center / Downloads" page.

While the pictures are for a 1970 Chevelle (which shares the same rear window as the 1969 & 1970 Monte Carlo as well as other GM A-Bodies), this guide will work for any car.
