I was looking through the dealer brochure for my '85 Thunderbird at all the options you could get. I didn't see that a trunk-mounted luggage rack was on the list of options. However, my '85 has a luggage rack that looks like it was factory installed. Could it have been a dealer installed option?
Here's another picture
This is pretty awesome. Never seen a luggage rack for these cars either..
Dealer installed.
Ok, cool! That's what I was hoping for. It would be interesting to see how many Thundercats had the luggage rack installed.
