Swinger rarity...

They're not any more rare than any of the other Mopar's of the era. Quite the opposite in my experience. A "swinger" is just a 2-door hard top from '70 up, unless it had a higher option package. Like my '71 GT's, they're 2-door hardtops but NOT swingers. I did send one to the crusher myself, a '74 with a 318. I bought it for the roof skin to fix one of my '71 GT's and all the 73+ V8 parts- K frame, disk brakes, etc. It had been hit hard in the back, and the chassis up through the doors was bent. After I stripped all the good stuff I sold it to pick-n-pull, it got stripped down even further there. Was a shame, it was a good rust free California car, but the chassis work needed to get it straight again would have cost more than the car.

Heck, there's like 9 of them that show up on a craigslist search for the greater Sacramento area.
