Possible suspension swap

Thanks for the info!! I figured it was a '73 or newer. I have a potential donor car (mid 70's Dart Sport) for some of the little things - Like I need a heater core cover, the seats I have came from a Ford ZX2, but if I can get factory buckets from another a-body that'd be preferable. Not sure how much I can use from a Dart Sport, but it's an a body so it's a start. Hoping it has an 8.25 rear end with the bigger bolt pattern.
if you were closer, theres a guy local to me selling some factory a body buckets but the shipping would be $$$$
