Hey all, I'm trying to order from Eckler's catalog and I need a passengers side, mirror. I know that my car does have the rectangular shaped mirrors, but am unsure of which eckler's part I need. The catalog shows p/n 603319 as "68-72 passenger, 69". As well as p/n 606037 "70-72 either side, correct"
Can you guys shed some light on this for me?

I forgot to add, I've got a 1970 malibu
