I have confirmed something I had suspected for a while now. Superior used one grommet for there glass it was formed so that it will go either right or left. all I have had apart up to now were back door glass. they looked to me like that was the case. but now with the glass in this 63 ambulance I can definitely tell they are reversible. makes since to only have made one set of them and used it either left or right. if you have one that shows damage on the out side. during your restoration you can trade them. put the side that has been out of the weather inside and the nice side out. a little wd-40 sprayed liberally will soften the rubber to like new making it easier to handle.
