Bucket Seats - Some Questions

Alright, I had wanted to put in the set of Dodge Avenger buckets I had in storage into my Dart, but my dad was dead set against the idea of custom making brackets to make them fit, so I sold them to a friend whos wanted them for a while...
Anyway, now I'm on the hunt for some buckets for my Dart.
I know that the ones from a Dart Sport/Duster will fit, but have yet to come across any anywhere.

I did, however, find a set that looks exactly like them in a 78 Dodge Aspen in my local junkyard.
They are white (ew), but they look like they should work.
I'm curious if anyone knows if they fit in a Dart without any custom work (but drilling the pre-dented holes)

Also, is there a place to buy the entire seats, reproduced?
I have found the upholstery, but not the seats themselves...

Also, if anyone has some buckets for sale, let me know.
