I'm not sure either, I just was looking at some pic's on the web and they look to be similar. There are rights and lefts on the 46 and earlier with 2 bolts that hold them to the cowl and 3 bolts to attach to the hood with a clutch head hinge pin. If I had a good chrome shop within a hundred miles of me I might have them repolished and rechromed, no such luck though. Guess I'll have to figure out "plan B".
