You should post a picture of the tag, and maybe try to make a pencil impression of it on paper, you have some digits off (the VIN has to be JH23G4B, not JH23G43, and the end with L2 458 is wrong too, there wan't be an "L" there, but I can't guess what should be there. Options are listed alphabetically, so it should either be a W or Y option, or the "26" which indicates a 26" radiator, which usually comes last)
You can do it yourself also, there for example :
http://www.mymopar.com/index.php?pid=87Just fill in the numbers in the same spots as they appear on your tag, and click Decode.
