Yeah, but they do show up
on eBay fairly often and occasionally in the local trading post. I'd buy a set and try them if I had something to pu them on if they won't work on my Dart. But I drive a Hemi Ram and my wife's got a 4.7 Jeep. It looks like the flange may need to be cut off and re-done a bit, but if the #1 pipe don't come down to low they might just work.
