There are multiple adjustments points on the 1968-1977
Corvette T-Tops. All of theouter 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. For additional information read our
