Great Story...

Just decoded the fender tag on a website..
I had taken a picture of it, so some of the info may be missing because I couldn't read it very well..
Does anybody know about the rarity of vehicles with certain options?
I also know it came with a factory AM/FM radio.

How do you know that it came from the factory with an AM-FM? It should have a corresponing code under the "R". You should be able to get the factory options list for your car from Chrysler Historical.
