1970 D80 spoiler question

[GeorgeLyons]

Could someone describe/photo the correct attachment nuts for the '70 Camaro spoiler (non 3 piece) to the deck lid. Mine looks to have some wrong ones and I would like to be sure as I put it back together.

[Jacsey 70Z]

They are a small nut with a captured washer on them, The middle attaching nuts have a larger washer then the four on the end. But, my original un restored car has the larger on the outside also, so someone messed up, or there was room on mine so the washer didn't hang over on the ends.

Mine also had a couple missing on the end, should be two.

The outer four nuts and the inner four nuts have different diameter captured washers. Just looked through ALL my different pics, including Marty Wrights, I cant find better pics than Jacks
Jack can you help us with this detail, before I write and ask other people for more pics.
George I will measure the two exact diameters. www.amkproducts.com (http://www.amkproducts.com) appears to have the correct fasteners in there catalog.

[John Brown]

By the looks of the pictures, the studs are different diameters. That would account for the different diameter washers.

[CamarosRus]

All studs have 1/4" Course thread. All Yellow Zinc nuts are 1/4" course with captured(moveable)washers with the little "teeth" that bite the metal. Small Dia washers measure .565 Dia and Larger Washer Dia is .750. I THINK small Dia washers should be on the four outside locations and the four larger dia washers fit the inside positions. This was due to outside mounting holes being CLOSE to edge of trunk lid.........

Found exact KEPS nuts on pages 48 AND 49 of www.amkproducts.com (http://www.amkproducts.com) catalog

Never had seen the rubber stops before. Learn something new every day. http://www.yenko.net/ubbthreads/images/graemlins/biggthumpup.gif

Wow great info. I will assume those nuts were used thru 72. Guess my car is a stripe/spoiler delete Z. How weird. http://www.yenko.net/ubbthreads/images/graemlins/crazy.gif

Kim, Regarding the Rubber Stops, WE (nastyz28) do not have conclusive proof as to when they were stopped on either Norwood or L.A. 1970 Camaros.
Jack, Did your Orange Camaro come to you with the missing KEPS nut......and it does seem likely that for some unknown reason, your car has the(incorrect)LARGE Dia washers/nuts in the outboard locations.

[Jacsey 70Z]

Yes Chuck, When I got the car two were missing and the others were finger tight. I'm sure this is the way the car came from the factory. For some reason my car seems to have more room between the hole and the edge of the deck lid. Look at Marty's car from the pictures I have his also look like the large washer. So here are two unrestored cars with large washers.

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 ?

[Rick H]

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?

Rick H.

[GeorgeLyons]

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.

[Kim_Howie]

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.

[Jacsey 70Z]

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.
