quote "Some "A" introits don't like the "AR" term, but it is justified. Part numbers ended in an A suffix. After the redesign, so to speak, the Engineers went back and added the suffix "R" to the part numbers. R standing for "REPLACED". Thus giving us the term AR for these car. Not only were a large number of parts replaced, but the original car as designed was replaced because of this. This was major. It's not like they just changed a dimmer switch or add another tail light or something."
Thanks for the explanation of "AR" . I knew it was only on the early model a ,but didnt know what it stood for. Now i do.
