I am sure Neon seats would fit fine, try to find a 2 door so the seat fold up to allow room for rear passengers. I have the front buckets console and rear seats & belts out of a 05 Grand prix that fit in my 65 Dart. The width is perfect, I had to do a little tin work under the rear seat, and fabricate some brackets for the front seats and console. My quick silver shifter fits in perfectly. The rear seat bolted perfectly to the package tray and I can even fold down the rear seat to expose the trunk. :wav:
