Did you double check the width of the rims? Your car rims normally were 14x6. those are nice wheels for 70 series tires. My 66 polara and 66 Chrysler had 14x6, just a friendly suggestion/
My 69' window sticker for my coronet still refers to them as magnum 500's even with the beauty ring. 5.5 was standard. no 6.0 until 1970, and optional even then.
I bought these from a Dodge dealer in 2004 when they were going out of business. Any Interest? Two driver side doors, and the hood, new with the part numbers still on them. I'll look up the part #s to be sure they are 71, and not 72. Thanks!
