Newbie
New to forum, and new owner of 1997 GMC K1500. Wondering about abbreviations such as NBS and OBS. I have used other forums and there is usually a list somewhere. Am I overlooking it?

Those are the common terms that most of the forums these days go by. The thing is, in 2050 when we have the NNNNNNNNNNNNNNNNNBS it will be confusing.
The proper way to refer to them as is...
GMT400 (88-98)
GMT800 (99-06)
GMT900 (07+)
Agreed. Always wondered why they went from 400 to 800 though.
