i have that fender on a 1975. i guess the differences are in the hole count and locations for the crap that mounted on it under the hood.
but as for getting it on the cruiser, they are the same fender.
this guy has an oem fender, i think it still has the sticker on it.
He's a little unrealistic on the price, but if you let him know what toyota gets for them maybe he'll give you a deal. I drive by the guys house once a week if I can help coordinate.
