Question 1

What else is a 1999 GMC Sierra sold as?

Accepted Answer

A 1999 GMC Sierra is also sold as the Chevrolet Silverado in the USA. The Chevrolet Silverado is the same car under a different badge, so parts generally interchange.

Question 2

Do Chevrolet Silverado parts fit a GMC Sierra?

Accepted Answer

For a market twin like the Chevrolet Silverado, parts interchange in most cases because it is the same vehicle with different badging. Mechanical and service parts are the safest; lighting, bumpers and trim can differ between markets, and right-hand-drive versus left-hand-drive affects steering, mirrors and dashboards. Always check the part number against your own car before buying.

Question 3

What does GMT800 mean on a GMC Sierra?

Accepted Answer

GMT800 is the chassis or generation code for the 1999 GMC Sierra. Parts catalogues for older and imported cars are usually organised by chassis code rather than by model year, so it is the most reliable thing to search on.
