Alaskaskiff put me on to the idea of going down to the dealer, give the VIN, and have them print a build sheet. MAN YOU MUST GET ONE OF THESE! There is no cost - takes a few minutes - and has everything put on your truck - I mean everything - down to the hour it was built! I'm using this to determine exactly which front springs I have. Do yourself a favor and get one of these sheets.
Thanks Alaskaskiff for the heads up!
