This week’s Corvette Question comes from Anthony who owns a 1977 Corvette.
How do I adjust the T-Tops on my 1977 Corvette?
1968-1977 Corvette T-Top Latches
Answer: There are multiple adjustments points on the 1968-1977 Corvette T-Tops. All of the outer latches and center locks have adjustment points. To get your Corvette’s T-Tops to fit correctly, first loosen the latches and center locks. Next, fit the T-Tops to your Corvette, moving and sliding the T-Tops into the desired position. They should be flush from side to side and between 1/8″ to 1/4″ high at the rear roof. The glass roof panels were designed to fit from 1/8″ to 1/4″ higher than the rear roof so do not attempt to make the panels flush at the rear. Once you have them placed correctly, sit in your Corvette and begin to tighten the adjustment points. Both the latches and center locks have vertical adjustments in them as well. Your T-Top can be pulled down tighter by turning the adjustable bolt in the outer latches. When adjusting the bolt take notice of the clearance from the roof panel to the windshield header; there should be a minimum of 1/16″ gap. You want the rubber weatherstrip at the front of the T-Top to compress so that there are no leaks but you do not want it to be so tight that the T-Top actually lays on top of the windshield header molding. For the last adjustment simply add or delete shims to the center locks until the desired fit is achieved.
