Neat trick with the mirrors. And a welcome upgrade for sure. I suppose you could optionally do power mirrors if the client was inclined.Next, the attention focused on the side mirrors. These are GM “G” body side mirrors, and a small steel adapter shim plate makes them mount cleanly on the doors, rather than tip inward.
The panhard (or track bar, as GM called it) is factory on these cars. Although they have a 4-link rear, it is not a true triangulated 4-link as the Chevelle is. The upper arms are angled a bit, but it is much more of a parallel link than a triangulation. We would not have done much to the bar mount, but the customer wanted the tall aluminum differential cover with adjustable preload, so we had to extend the original mount. The earlier cars had 3 arms and the panhard bar from the factory.Why do you need a panhard bar with a factory-style four link that is angled?
