shorty headers

I'm curious if anyone knows if shorty headers for a Dakota will fit a '71 swinger with a 318? I have found a set that look to be new that are somewhat local that I can get pretty reasonable, the guy says they are for a dart but from all the pics I have found they seem to be Dakota headers, just don't wanna buy something that wont fit. I'm not dead set on headers by any means im ok with manifolds as long as they flow good for street use, but I don't really wanna do long tubes when I install a refreshed engine because I want the front end as low as possible and don't wanna drag everytime I go somewhere. even though I really enjoy the sound of a nice long tube header. thanks
