The windshield trim straight pieces are aluminum foil inside a clear plastic form. The corners are aluminum. The dimensions change occasionally so the pieces can get “out of sync”. r. d. enterprises has trim (slightly narrower than original) and corners that match. I know lotus-supplies has sets that I expect match up but don’t know first hand. Dave Bean is probably worth a call also. I don’t know who makes the straight pieces. I would imagine that suppliers come and go. I’m pretty sure that corners are commissioned by somebody like r. d., Dave Bean, or lotus-supplies and they distribute them to other suppliers. They are no longer available from Lotus so they are all reproductions.
