Good afternoon everybody! A previous owner removed the glove box RPO sticker, however I found a sheet under the bench seat titled "E/C Sequence Line Up No....". It's front and back, with 18 total lines. Is there any way to read this and figure out if this sheet points out which build is my truck? Three lines are not crossed out by red pencil. Any help you can provide would be greatly appreciated.
