Does anyone have pics of the underside of the trunk lid of a factory wing car or one that was installed correctly?

 

Joe P where are you when needed....lol 😂

 

I don't get the joke.

 

Not a joke, Joe P is our advisor/tech Guru. He will probably answer up and have some pics/specs. Welcome to the site!

 

Joe may be at the Muscle Car and Corvette Nationals (MACN).

 

OK thank you, I thought I asked a stupid noob question. Lol I haven't had a Cutlass since the mid 90's but hopefully I will be bringing one home soon and I'm going to need some advice. The restoration parts options have changed a lot since I was buying parts in high school.

 

What year and model car do you have?

 

This is a very good site.

This is my 1970 w30 car, it was not a factory wing car but added in the 80’s, done correctly, centered correctly. Hope this helps.

 

Nothing yet but I wanted to see how the factory installed them on the 70-72 Supreme. When I put one on my car in high school I just winged it and put it where it looked right and drilled some holes and bolted it on. Would rather do it correctly this time.

 

You are going to have some trouble positioning the wing where the factory installed them on 70-72 Supremes because the rear wing was not available on 70-71 Supremes or convertibles. Also, the wing was not available from the factory in 72 at all.

 

There are pages in the 70 and 71 assembly manuals that show the correct mounting location and exact hole positioning with measurements for "fast backs" (holiday coupes and post coupes). You could use these as a guide if you want to mount a wing on a Supreme trunk lid, although the lids are slightly different between the Supremes and holiday coupes.

 

I thought 70 was the last year it was available and I'd have sworn I read they were available on the 70 Supreme. Regardless, I want to see the underside to see how they were correctly installed and the correct hardware they were attached with, even on a Cutlass.

 

Same picture that's in the 1970 PIM is in the 71 PIM. With updates. 70 version was dated 10/10/69 and the 71 version was 01/22/1970. But the location and dimensions are the same. Here's the 1970 version:

 

I was able to find that but nothing from the underside showing the correct hardware.

 

Kind of surprised nobody has stepped up with a factory wing shot. Maybe that tells you just how rare it was from the factory. As was said before. Wing was never available on a Supreme.

 

I've been mistaken all these years. I thought they were 70 only on the Supreme but apparently they were dealer installed so that could be what I've been thinking of. Regardless, if I get one it will have one and I still want to see the factory mounting hardware inside the trunk, regardless of what car it is. In high school I used hardware store bolts and washers but I'm assuming this isn't how GM did it! lol

 

There has to be someone here with a factory wing car.

 

Figured there would be at least one Rallye 350 or Hurst/Olds🤔 But it's the holiday season and people are busy so no worries.

 

Honestly I am surprised too. Wings on cars are more common now than they were factory. There has to be an example of one here.

 

There are a couple pics posted but I want to see factory original hardware.

 

According to BlackGold on this site, the rarity of the rear wing is reinforced by the numbers. Only 294 cars or 1.8% of the coupes presented with the rear wing, part number 983190, beginning in January 1970.

The pictures Andy posted are representative of the factory W35 option. Three studs on each side of the wing attached with 6 nuts, the center stud being the longer of the 3. The only exception I note is the particular nuts used in this example, as they should be flange nuts.

 

Yes, I would like to see a few pics of original mounting/ mounting hardware as well..as I stated mine was added by the second owner in 1988, he at that time added power windows as well. It is an original wing.

 

I tend to agree with you about the wing's originality on your car.

 

 

Tried my best to get the photos downloaded as clear as possible.

 

Very cool info, thanks for posting…wonder how many were sold?

 

Hope this helps

 

Absolutely perfect and just what I was looking for. Thank you!
