if you have a rear antenna you did not get a spoiler, regardless of radio ordered.
Completely agree Joey, but
ONLY from the factory. Dealers were free to install almost anything you wanted!
When the 1968 Price Schedule was produced was prior the the Dealer Installed Spoiler was an option.
That's not correct. The "dealer installed" spoiler was available late in the 1967 model year, so by the time the 68's were rolling off the assembly line, they could be ordered from the factory (RPO D80) or added by the dealer (which was called "Extension, Luggage Compartment Lid", Group 12.181, P/N 3916633).
If you ordered an AM radio (RPO U63) with the optional rear mounted antenna (RPO U73), the factory said no, sorry pal, ain't gonna happen! However, dealers would do anything you wanted.
So if a buyer wanted the dealer installed rear spoiler and also wanted a radio that called for a rear antenna...
There wasn't a radio that "
called for a rear antenna". The rear mounted antenna was factory option RPO U73 and had to be purchased separately. And from the factory, it was only available with the AM radio, and, as you stated, NOT with the spoiler. However, as I stated above, dealer installed accessories weren't regulated so they were free to do almost anything you wanted, which included adding a rear antenna and spoiler!)
