69 Z D-80 Option ??

[TX-302]

I've seen cowl tags stamped with the D80 RPO and many tags without the stamp. CRG info states front and rear spoilers were optional on early/mid 69 Camaros and standard on late models. Does that mean all the (early or late) Camaros equipped with factory installed spoliers had the D80 stamping and all others w/o the stamped tag may have had them installed by the dealer?

Here's a previous thread on the D80 option.  I knew it was posted just had to find it.
