Welcome aboard.
ViperDave: your post says "bird" but your profile says 71 Charger. Huh?
If you got a Road Runner, and it's a 999 code, that would be a 1968. And 1968 RRs weren't available with 440s. Huh?
So I'm guessing you have a 69 or 70, the code is 99 99, and it's rare. Right? Petty Blue, yes, rare. I know of 4 for 68, 1 for 69, and 1 for 70 (confirmed by tag and sheet with 999 or 99 99 Petty Blue). I'm sure my lists are not complete, so it's always great to confirm the rare-est of the rare.
I'd love to see the fender tag and share info I have with you. Send a PM and post them pics (still hungover from the 4th?:sleepy2
