I know they don't match your interior center front windsheild trim, but it is coincidental that that peice is identical in length, width, and shap as the one on my 50 3600. Only differce is mine has four screw holes not two. This item is to small to be used for anytype of structual support which is why I am quessing it must be a interior trim piece.

I'm slow, but consistent........consistently slow!
