Difference in assembly line vs. nos 69 Camaro core supports

[MosportGreen66]

Gents, are there differences? While I’m comparing OEM GM to NOS GM I’m sure there could be differences. Any help identifying these differences would be great.

Thanks,
Dan

Sold many of them in my CPX days. The top rail on service replacement supports was badly wrinkled. Production core supports were smooth. Date stamped near the VR.

Here in the rust belt, rust holes at the bottom under the core not unusual. Also, rust near the battery.

Any pictures showing exactly where the date stamp is William? Inside of the core or the outside face...and its positioning in reference to the VR location?

I appreciate what you can share. Thanks

William is correct regarding the later NOS with exaggerated wrinkle on both ends on top rail. I also believe later NOS lacked the AC provision/holes on the top rail. Perhaps only on later NOS ones.

I weighed a reproduction with an original and the reproduction was like 2 pounds lighter. You could feel it holding them. Kind of shocking. Says something for strength of an original

Seems appropriate to point out production '67 & '68 Camaro core supports were different than '69.

They did not have the holes on the lip of the top rail as the a/c condenser mounted differently. Also, had larger VR mounting holes for the well nuts not used in '69.

Early 69 cars had the rubber isolators and later in production they went to fixed mounted vr IIRC.

Thanks Mike...

Looks like mine is stamped 43 for the 3rd week of October. Thanks for that location as my eyes aren't as sharp as they were several years ago. Doubt I would have saw that if I done ditn't get told where't was. (lol)
