where can i find the gutter guard? over the door on a 1972 cutlass supreme passenger side door ! the piece is chrome

 

OK, if your describing what I think you are it's stainless steel that "snaps" over the metal drip rail. I don't believe this is reproduced so you'll have to find an original piece. Be careful in removing it, it's easy to damage it. One of the guys here taught me to use the old "church key" can/bottle opener. Wrap the rounded end of the can opener in a couple layers of electrical tape. Then gently start prying the stainless up and off. If your gentle and don't get in a hurry you can remove it without bending it and be able to snap it onto your project car. Try posting a parts wanted ad and see if someone on the board has a parts car with the trim. I believe 1970-72 Cutlass Supreme are all the same for this piece. John
