I'm trying to determine if the 68 short spoiler #3916633 all had a long stud with what JohnZ stated the plant called a "dog point" meaning the end of the long stud was undercut at end and the long 69 #3949798 spoiler came equipped with a long stud threaded to the end.
Can you please open those trunk lids and check configuration on that long spoiler stud? Undercut on end or threaded to stud end?
Thanks everyone,

This is my original spoiler on the original lid. Does this help? LA built 3/13/1968

Sorry for my off-topic post, but I just have to comment on how much I LOVE a '68 in Corvette Bronze! and a Z28 no less! :)

Thank you. Had it a long time...like 45 years...Joe

Thanks Jim and Joe! Yes Joe that helps in more ways than just the dog point long studs. You can really note the glue residue for the posi label.

Chick. That's not the original sticker. the original was a mess so when I had the car painted I recreated the mess with the glue. Not bad eh?...Joe

Joe, I HOPE the runs were there and I am not assuming they were - so I commend you on reproducing the runs in the paint... most lack the nerve to FAITHFULLY stick to how it was from the factory, especially flaws likw runs.

James, what have u found on configuration of long studs 68 spoiler vs 69 spoiler.

Here is a photo of a early LA car 09B - it has the narrow or "short" spoiler, in fact so early it has the 68 style stripes on the deck lid -
IT appears to have a dog point stud.

Where is everyone LOL......
I'm confident the short spoilers had the undercut on the end of the long stud (called dog point per Johnz) but can we have some pics of different time periods of the long 69 spoiler? Trying to determine if they were all threaded to end of long stud.
Greatly appreciated!

My late '69 Z28 - 09C - 18Sep69 production - with std long '69 spoiler has what appears to be studs that are not 'dog point'...

Gary does your stud have a built in washer on the short side of the thread that screw into the spoiler .

Yes, they do. When I purchased my car, there was water coming into the trunk, and after a while I figured out that it coming in around one of the spoiler mounting holes (a stud had broken off). I had a pretty difficult time finding a replacement stud and nut (a type of shoulder nut). Here are photos showing both a short and long spoiler stud and the nuts, and looking at the first photo, it does appear that there's a 'slight dog-point' tip on the studs.

Thanks Gary that's exactly what i have , does all long spoilers have these studs

No "Dog" there, tapered thread, Tapered stock
Minor clarification

Jim, assume your referencing your 69, correct? Do either of your 68's have spoiler? If so, do they have dog point long studs?

Pictures of rear spoiler mounting. October 68 LOS built. Short spoiler and short stripes (Stripe dimensions match assembly manual).
Spoiler bolts I think are dog ear. See picts.

It is my belief that:
The 68 short spoiler #3916633 GM spoiler 40-2259-GB uses; Three lengths of Studs,
Double ended, 1/4-20unc x X (plus 1/4")" x 1/4-12, 1/4-20unc machine screw thread end Dog Point, 1/4-12 wood screw thread, blunt.
Qty: Y
Length: X (Exposed Machine Thread- including dog point)
Root Length: Equal __1/2"__ on ALL (Root is the wood screw thread portion- Blunt)
The Stud at emblem position is the Med, The studs at the deck lid edge are the Shorts, the remainder of the studs are Longs;
Shorts: Y = 4 each, X = 1/2"
Meds: 1 each, X = 1"
Longs: 3 each, X = 1-1/4"
Dog points machined to thread root diameter and length appx equal to or less than 1/4"
The nice thing is the hardware aftermarket is fully supported via McMaster-Carr 1/4-20 x 3" Hanger Bolt Zinc Plated can be sourced and machined via a lathe or other means to replicate damaged or missing studs. 1 package contains 25 each, HXA04096MC 90207A310 Cut down and turned as needed to replicate replacements as a DIY
69's seem to be a different animal (Not Dog point end)
Both My 68s have owner modified early in life with Short Spoiler of GM fabrication & are both equipped as described above.
My 69Z11 have studs like Gary's 69Z.

Are the emblem holes welded or brazed shut in the photo of the hugger orange october built car?
-
Not sure. How do you determine that?
-
In your photo of the right side spoiler studs - there appears to be weld beads or brazing in the exact place one would normally expect to see holes or emblem studs.

The weld beads on the right side spoiler studs appear to be brazed. The beads are brass in color and would be where the deck lid "Camaro" emblem would
have been mounted. My car (hugger orange) did not come with a deck lid "Camaro" emblem. The build sheet lists "05D80AA", Air spoiler equipment
as one of the options.
-
When a car, such as yours, is factory equipped with a spoiler, the 2nd set of holes for the emblem is not optional, they were done by the same "combination drill tooling" at the same time the deck lid was drilled for the spoiler.
According to a post on the subject by: JohnZ
"The second set of emblem holes were fixture-drilled in the Body Shop, using the same combination drill fixture used for the spoiler attaching holes, before the body went to the Paint Shop."

Good to know, interesting fact. By the way my deck lid stripes do not extend
to the bottom of the trunk lid, as seen on other 69z's.
Thank you

Correct, they should not extend to the bottom of the trunk lid
-
My apologies, the rear deck stripes do extend to the bottom back of the trunk lid.
The paint is original as well. I have never seen any indications of a rear end
accident as well.
-
ASM69: The cars that had their spoiler 'factory installed', do NOT have stripes under the spoiler (and the stripes do not extend onto the rear of the deck lid - the stripes were masked at the bottom of the spoiler. Your car also has the 'holes' in the deck lid that were factory punched for emblems; yours are brazed up. That is not 'factory either. Your spoiler was perhaps installed by the dealer or sometime after that.
-
Great information. The build sheet lists "05D80AA", Air spoiler equipment as one of the options. So, I think that indicates that the spoiler was
to be installed during the build. So, maybe the spoiler wasn't available during the build or since my stripes begin about 5 inches below the bottom
the rear glass (as though it had a vinyl top) maybe the excess stripe material covered the area under the rear spoiler and extending down the
back of the trunk lid. I hope your can follow that. It's a thought.

Can u post a pic of your build sheet?
