1966 Chateau Slate L78 Chevelle

Hi Mitch, You have to cut them to mimic what the originals did to allow the gasket to form and flow around the corners. You just have to be careful and use a razor blade or xacto knife. Based on what I can see of the originals, they already had the relief cuts in them for a production setting.

OK, that is what I did and they look OK, I think I needed to cut just a little deeper as they still wanted to buckle. I have to take them off again sometime, so I'll make a slight "adjustment". Yours lay very flat and look original.
