Hello, I have a 1979 Plymouth Volare Duster with the full size quarter windows and louvers. The metal tabs on my louver are fine, however I’m missing two of the three plastic clips that clip into the inside of the chassis and hold the window in place when the epoxy is applied. Is there a place where I can find these parts, or an alternative work around? Will be replacing window in the near future. Thank you so much, Erik
