Can someone tell me if every 69 RS/Z28 was supposed to have the "Chrome" roof drip moulding. Also what is the procedure for installing this moulding...Thanks for any and all responses...BBS..

Lay all the mouldings out on the floor. If you look very carefully, you will notice small differences in size at the ends of some of them. These smaller ends go under the ajacent mouldings. Once you lay them out, you will see what I mean.
As for installing them, let's hope they were not stretched when they were taken off. They are a friction fit moulding and have to be in the proper shape or they will come off as you travel down the road.
You can use some 3M seam sealer to secure them and wipe off any extra after they are installed.
