96 Outer Air Dam Screws

[Pat M.]

I'm interested in the screw sizes, numbers and configuration that hold the two outer air dams. I believe there are 7 screw holes, but the service manual only shows 5 being filled, the outer 2 and the middle 3.

Could people with known originals tell me if all your screws are the same size, how many, and if they're configured as the service manual shows them? Pics would be nice if possible.

Thanks.

Hey Pat.

The 96 I have here today has the 5 bolt configuration. Here is one I just pulled for ya ! 10mm socket removed it.

No real head mark but a circle.

Re: 96 Outer Air Dam Screws

Thanks guys. Tom, all the screws are the same size as the one in your photo?

Any additional responses would be appreciated.

Re: 96 Outer Air Dam Screws

Pat, they all appear to be the same.

Pat, here are the instructions. E-mail for some photos.

Thanks again Tom and Charlie. Charlie, where did that instruction sheet come from? It's similar, but has more information, than the service manual picture.

Re: 96 Outer Air Dam Screws

The picture Charlie ( Pat ) posted is the sheet that came in the cars. That was the dealer instructions for prepping in the car and installing the front air dam and front facia license filler.

Pat, the attached photo is from a data base of photos I have that were taken of a 1990 Corvette that never made it into the dealership. The air dam was shipped in a plastic bag and installed at the dealership. I got my instruction sheet when the dealer ordered a NOS Air Dam Set for me a couple of years ago.

Re: 96 Outer Air Dam Screws

Pat and Tom.

Attached are two photos of my original air dam installation, You will note that it was installed incorrectly at the dealership. The support bracket is between the air dam and the body and in this manner provides no support to the plastic air dam. Also the bolts for the front air dam go two ways. The middle ones are pointed down and the end ones are pointed up.

Re: 96 Outer Air Dam Screws

Here are some grill photos. It looks like in its early life it was bent a little.
You will notice that the end screws point up and the middle ones point down.

Re: 96 Outer Air Dam Screws

OK, now I'm really confused. I'm trying to figure out if my dealer installed them correctly as well.

Apparently there are 3 metal retainers for each dam (or deflector). I believe the middle dam retainer should be below the plastic dam, and all of the bolts should face down, according to the SM and Instruction Sheet.

On the outer dams - should the metal retainer be below the plastic dams (as apparently shown by the SM and instruction sheet), or above them inside the bumper assembly? I can't see how they could work if the outer metal retainers (with nylon nuts) are below the plastic dams?

Comments please? And pics of all three metal retainers, with screws/bolts installed, would really help. Thanks

Re: 96 Outer Air Dam Screws

Pat, The center metal retainer is on top of center (air deflector) spoiler section. Bolted down with 10MM machine screws.(head up) The ones Tom has shown in picture are the 10MM self tapping that are used for the left & right air deflectors. There are NO nylon nuts for those. My 95 came in with no spoiler.I called Bowling Green and I spoke with Sonny Kilgo on the Corvette HotLine back then. He sent me a complete Deflector package for my 95.
I am One Corvette Nut that I looked at other Corvettes and installed the spoiler myself. Told the dealer NOT to Prep or touch my Corvette when it came, or I would not take it. I have done that with all my new Corvettes. So here are some pics, hope this helps. PS I was so crazy that I thought I was going to keep my 95 forever so I ordered three extra complete Left & Rght and Center Spoiler Sections. Had to keep sending them back to get the most perfect ones from GM parts. (No mold damage) My GM parts guy knew I was crazy but we got the best ones anyway. Save the Wave.>George

Re: 96 Outer Air Dam Screws

More pic's 91-96 Spoilers. Missing the silver center section, gave away to a friend back in 97. The center 10MM bolts are about a (flat end)quarter inch shorter with no pointed end using 10MM HEX machine nut. Another thing I meant to say, back in the day when 91-96 Corvettes were new I saw alot of Chevrolet Dealers FAILED to install the Center Air Deflector Brace.GM part number 10149267 ( discontinued ). Thought you like to know what I observed back in the day. Save the Wave.>George

Re: 96 Outer Air Dam Screws

Pat, Thought I had a closer pic of front spoiler on my 95. You can see the silver metal section on top of my center spoiler. Correct. Save the Wave.>George
