evening Drew, not corrugated. don't know if i still have the glass, might have gotten rid of the sides but don't remember lol. i'll have to ask sam. probably the most effective mod i did was replacing the side glass with sliding windowsRon is a '69 the corrugated sides? If it is the regular glass, I'll bite. I have a set of sides in the shed with gaskets but no glass. If they can play nice together I am intersted.
