1981 seats in to a 1995 softdash could be a bit tricky, if I remember correctly the seat bases are totally different so some modification would be needed, the dooor cards are totally different so wouldnt fit, 81 had large wood panels that were not part of the door card but lay over the top part of the card covering the upper 3 inches or so. It would be easier to look for a leather interior complete with cards from a late classic as these should fit with no problems, although the seats will probably be electric so will need to be wired in.
