Hi, new to the forum and am in the process of buying a 69 AMX 390 4sp car.

On the door tag under BODY there is the number R031373 what does that decode to?

Also at the bottem of the tag there is just the number 5078490, what does that decode to?

Should the car have 14x6 or 14x7 wheels?

What tires should a 69 have? redlines or white letter Goodyear polyglass?

What size.

Thanks to all for the help,
