My car had new doors on it when I got it. The top of the doors on the outside should have about 6 studs on them to attach the clips that hold the bright trim on the top of the door correct ?

I recently installed the Z21 upper door stainless trim on my Aug built Z28 . I purchased short self taping screws from home depot and drilled correctly spaced holes along the door panel and installed them with the proper clips. Just measure 1/4 inch down from top of door skin and install. Then install trim to top of clip then roll over to bottom and they will snap in place. I can try to post pics if required.

Forgot to mention pilot holes will need to be drilled. Not to worry if you drill through the inner door frame as the outer window sweep will cover almost anything.

If you drill into paint, watch out for chips of paint flying off even with tape on it. Paint is hard.
Pics of process to install Z21 door upper mouldings. Sorry if they are not in order.

GM used these.

I think those screws were the GM "repair" solution for a broken nelson stud. The cars came from the factory with welded nelson studs for the trim clips.

Those screws are what I used to add the Z21 trim to my 73. The stud placement was 3/16" from the top of the door. I suppose 1/4" should work, but if you want to be exact, go 3/16".
