Hello dv8,
Welcome to this site.
First, if you want an original seat, post a want ad in the Swap Meet (link is at the top of this page).
Next, if you want an original seat, have patience. There seems to be plenty of people looking to change to bucket seats.
If, however, you are looking for advice on what type of bench seat will work, you will probably get some good advice from people posting here.
