It has a part number but I couldn't tell you what it is. They were used on the Trans-Am race cars. I got that from a friend whose boss' brother worked on a Trans-Am team.

It's possible that these panels were *added* to certain small black T/A cars (by some race teams) for aerodynamic purposes....?  to 'slick' up the bottom of the chassis?

I received the re-pro 396 air shield from Ed Melberg, it is a really nice piece. I cant fit it to the car but I attached it to the core support and took some pictures.
x66 714 Thanks for your help.

Is that somebody on this website? ..or, do you have any contact information and price on this item please?

Those of you wishing to purchase a new reproduction can contact Ed at edmelberg@zoominternet.net. Leave your phone number & he will call you back. They are very nice. He has about 36 left. Regretably with the low demand & the expense of making these the cost is a little up there...Joe

BlackoutSteve
I just revisited this post and looked back on the old posts where you wondered if they actually were installed at the factory. I worked at Jack Douglas Chevrolet back when these cars were 2 years old and don't remember the shields.
I found out by finding the holes on my core support and was going to weld them up before powder coating. Glad I didn't, curiocity prevailed this time. At the time I posted the picture I couldn't mount it to the car, but I looked for the holes in the subframe. They are there and one of the screws still has some of the plastic attached. I am sure most of these got torn up on parking curbs. The shield Ed makes looks really nice and matches any pictures I have seen.

Unless your sheild was adapted from another car, you are the only person so far to have any evidence of having one..
Not at all saying that you aren't correct about your information, but where are all the others I wonder.  Smiley

I've had my car for 29 years & those bolts & plastic that were spoke of still existed on my car also. Some of the other members of this group still had the piece in place on their cars. I looked for year to find this piece & I kept hounding the guy when I knen he was doing them. If you have a big block car w/air conditioning & it's still intact, i.e. original subframe & original core support, then most likely you'll find those holes. The car I have is an 08E 1969......Joe

Thanks to this thread and those who have helped me, I have been in touch with Ed and purchased a shield from him. It's currently on the slow-boat to me here in Australia.. I look forward to receiving it soon. Thank you.  Wink

However, as I prepare for it's installation, I noted in the FAIM (C60-B4) that the screw #9420825 is not available through AMK..

Can somebody who has an original screw post some details and especially a picture -if possible, so I can order the closest available.

Hex size, flanged?, thread size, pitch, with self tapping flute?, UHL (under head length) and finish.

Going by P. Washer #9419275 (currently available from AMK as B-11266) and the 0.277-0.281" diameter holes to be drilled, I'm assuming a 5/16-18 with a tapping flute in an oil/phosphate finish.

Thanks again.  Smiley

Hi Steve, good to see you here!  Smiley
Yes, I can also vouch for the Plastex stuff - brilliant, especially the moulding bar!! Used it to re-create a bunch of mounting tabs on a VL Calais.

Steve & z10kl, I can't seem to find the screws I took out of my subframe, I will find them & take pictures. I checked and all my holes are 3/8" X 16. If i remember they were same as front fender bolts,tapered end, with a recess in the center of the bolt head. I wish I took a picture of them before I pulled them, but I didn't know I was missing the air shield. Here is a very ugly picture of the subframe before disassembling. I pointed out the screws & holes.

Steve: I have to tell you I was amazed & entertained for many hours over the Christmas holiday at what you have posted on the Australian muscle car forum. What you have been able to do in what appears as a small moderately equipted garage is amazing and shows you are very talented. Anybody that likes Camaro builds needs to check the link under his name.

Mark x22, you are correct 5/16" bolts. I have been looking at too many metrics or just can't see like I used to. Anyway I pulled out my subframe and shield to bolt it up.
The 2 bolts that go directly into the cross member are 5/16 with a .280" hole. But the other 4  holes only measure .250" so I don't know what screws go in there.The holes are not stripped, a 1/4" fastener is too small.

Do you not have the bolts that came out of the holes?
