Once the dashpad is glued to the aluminum dashpanel and allowed to set up, carefully cut out the gauge, switch, and light openings. Resist the temptation to make pie cuts for the gauge holes. Instead, cut the vinyl padding about 3/8 inch shy of the metal hole. This will leave a padded "ring" that will place tension on the gauge assembly and give you a nice, clean assembly. Continue with the remaining holes in your dash.
