Thanks again Allen.

What do you know about the AO4 "basic group" My RED BOOK lists it as a $297.85 option but doesn't go into detail about what that gets you. My guess is that Dad's car doesn't have it because it has the R11 AM radio and the RED BOOK says that that option is WITHOUT AO4.

Also I have a discrepincy on one code. The RED BOOK says that J54 is the sport hood that is standard with A57 and the 340. The breakdown I got through "StockDodge.com" says that J54 is a hood insulating pad. Which is correct?

Are you getting your information from a website or do you have literature that has the codes broken out?
