C4 Corvette Roof Installation

Downloadable Instructions

 

Please Read-    The first thing you want to do when purchasing a new roof is verify the year of the roof on your car. Even though your car may be a 1988 it could have been converted at one point. Sound unlikely? GM sold a kit for many years to convert 84-88 Corvettes to the third design 89-96 roof styles.  Likewise, some people may find a deal at a swap meet and then convert their car to adapt that roof.  So, how do I determine my roof year design? You can compare your front mounting hardware with chart below or measure between your front mounting bolts.  Center to center of ea bolt hole usually gets close enough.

 

  • 1st design 84 - Early 86 28.5”

  • 2nd design Late 86-88 31.5”

  • 3rd design 89-96 32.5”

You can also look at the plastic trim covers on top of your windshield frame and compare with below photo

 

Once you have determined the year roof your vehicle requires we can discuss how to properly install it.  Start by parking your vehicle on flat ground, and inflating all tires to factory specs then follow the instructions below per your specific vehicle year.

Below is a video that demonstrates how to raise or lower the front of the roof panel. 

 

NOTES:

  • There are many people installing cheap aftermarket weatherstrips on their cars these days. Sometimes you don’t have a choice, but if you do, always try to find something as close to the factory latex covered foam type weatherstripping. Avoid the rubber (gummy bear) feeling stuff. It doesn’t compress very well and causes damage in many cases to Corvette transparent roofs. If you install these on your car you must readjust your front mounting brackets.

  • Shims may be added or removed behind rear brackets to adjust rear roof gap, though this is most often not
