1970 D80 spoiler question

[GeorgeLyons]

My rubber bumpers were attached to the underside with the same screw as the metal plate. I never saw one like the picture attached at the outer edge with a separate screw. What's the story ?

What else is interesting is the rubber stoppers are located in two different locations. Not sure why this would be if the cars bodywork was the same. It would be interesting to see where these contact the quarter panels. If they do at all.
I can't check my car because my 06B Z/28 has the three piece spoiler.
Anybody else have pictures of the one piece spoiler ends?

My car with the center mounted bumpers had dents on top of both quarters where these things made contact. Bumpers are quite hard rubber and quarter has no support in this area, very easy to dent, poor design. Spoiler could never hit quarters, why they put these on is a mystery.

Were the rubbers screwed in to that plate?? My plates have no holes? But don't think my car came with a spoiler from the factory.

I've never seen the bumpers attached using the same screw as the cover before something I'll watch for.
My Orange car has the bumpers out near the ends and the same on both sides. The Black car (4000 mile car) has one in the middle (like in the pic) and the other side out near the end, totally different from one side to the other.
The Green car also a original owner car has no bumper, it's a last week of Feb. Norwood car. I believe the bumpers started sometime in March but have'nt got it narrowed down yet. I think the bumpers were added to support the ends of the spoiler so they wouldn't crack or break if someone leaned on them.
I've seem where some hit the quarter panel and some 3/4" above, so I don't think they had it down as to were to put them.
