drip rail insert...

This is kind of a parts wanted question...but also a resto one as well. It seems that in 1969 the factory installed a flexible plastic trim insert into the drip rail to finish off the vinyl top. It is 3/8" wide with a chrome strip 1/4" wide and a clear edge. I think it was in a roll and cut to fit...I am working on the 69 granny and the drivers side piece is broken...might be able to glue it..BUT..?? any ideas on sources for this product or suitable replacement...thanks.
