I bought seat covers for my '67 Fury and '66 Barracuda from Legendary. I bought front and rear covers for both cars, but I bought them a few years apart.
The rear bench portion of the rear seats for BOTH cars did not fit correctly. I took measurements from my originals against their re-pops and e-mailed the photos to Legendary. They asked me to send my originals and theirs back to them (they paid the shipping), and they used my originals to make the pattern for the new re-pops.
I got them back a couple of weeks later, installed them, and they fit great. Customer service was very cooperative and polite. I don't remember the reps name now, but he was very professional in handling my case. I'm very pleased with the fit and quality of the Legendary covers. I've had them on the Fury for eight years now and they still look new.
You might want to shop around for the carpet for that Barracuda. Check ACC's website, RockAuto, Legendary. The last I knew, Legendary carries ACC and probably marks up the price. Like I said, shop around.
These are the only pics I can find at the moment. All upholstery work was done in my basement.
