Is your Charger a pre-Jan. '69 car with the full VIN# stamped on it?

& you're saying it has XP29F9B123456 stamped on a 383 block & your VIN# is XP29H9B123456?

I've seen a 440 block with the same deal - GOT a pic? I think I have a pic of the 440, I'll see if I can find it. (bet they're same day, on the line)
