1984 seats in my 1973

I have the opportunity to purchase a set of seats from a 1984 vette. I am curious as to whether they will fit in the car and if so is the intallation difficult. Any advise would be appreciated. THX

I installed '84 seats into my '76. I used the '76 rails because the new seats did not have rails. I had to fabricate mounting blocks to adapt the seat to the old rails. Overall I sit about 2" higher with the newer seats. I like them.

Thanks for the info, sitting a little higher would be great.
