Not Bob but the rivets are 1/8" black head - not sure of the length but fairly easy to figure from an examination. I bought some black coated ones when I re-worked my side curtains and found it's almost impossible to install them without some coating damage. It's just as easy to use standard aluminum rivets and touch them up afterwards with a small brush and some black paint. Drilling the rivets out is the approach to separating the frame pieces and replacing the plexiglass. Seeing as you are right there in CT taking them over to ERA would be a good idea;
