Re: Trying to identify gmc suburban

Now you've given us something to work with:

1GKEV16K8HF516402

1 = US manufacturer
G = GM
K = GMC nameplate, "multipurpose" vehicle
E=brake system
V= 4wd (formerly "K")
1 = 1/2 ton
6 = Suburban
K=5.7L V8
8=randomized check digit

H = 1987 model year
F = Flint Assembly (Line 1 = pickup; Line 2 = Blazer/Suburban)
516402 = sequential portion of VIN

So: it's a '87 1/2 ton 4wd GMC Suburban with a 350 cubic inch small block Chevy engine, built in Flint, Michigan. We can either tell for certain or guess pretty much everything about that truck except the colors based on that.

The label in the glove box is called the "SPID" ("Service Parts ID") label. The codes that populate the label are the "RPO" (Regular Production Option) codes, consisting of the optional content on the vehicle so that you can get the correct parts. You can get more information on them from the link I posted above, or find an "RPO decoder" and type them in individually. The order number is referencing the original order placed by the dealer to get the truck built. The truck is tracked by the order number until it is assigned to the final assembly location and is the truck's "name" until the plant identifiers (PVI and general assembly sequence numbers) are established. It doesn't mean anything to anyone anymore. Once the vehicle leaves the plant the VIN takes precedence.
