Questions about a 66 Baracuda

Let's see, what I can say for sure, is all the sheet metal except for the doors, hood, doghouse and trunk lid, as well as the bumpers, taillights, grille, front buckets seats, gage cluster and dash trim are specific to '66 only. Collectible?... not that I've seen, but they are great cars. Hood, bumpers and front fenders do interchange with '66 Valiant.
