1964 Dart seats

Seats from a 64/65 (and possibly a 63) should be a direct bolt-in. 66 seats can be used; however, the spacing front to back on the floor mounting studs is different than the 64/65. On my 65 GT convertible with buckets, it had the mounting holes for the buckets as well as mounting holes for a bench seat. Those holes have plugs in them.
