Is there any place that really has a breakdown as to what RPO codes really mean? I mean some of them are pretty obvious like LB9 is listed as a 305 tpi motor is equipt thats pretty strait foward but others are very vauge as to what it actually means. For example i dont remeber the specific code off hand now but it referenced decal package 2 which i can guess is some decal package but what exactly is in it??? After comming across a few very vauge codes like that I wondered if anyone knew of a website that had more in depth detail as to what they meant? The car is an 86 T/A if it matters.
