1965 dart gt spring question

I just picked up a new to me 1965 dart and I'm trying to figure out what rear springs I have, it seems like the shackles inverted a long time ago but they never tried to fix it and I don't know if it can be corrected or if the springs just need swapped out. I've attached some pictures for reference, it has a really aggressive rake to it but I can't figure out how much of it is the spring and how much is the tire. Right now it's running a 185/70/14 front and 205/75/14 rear. Any ideas on what I've got here?
