I've got what I'm pretty sure is a 1996 Weber 900 NG grill. I deduced the 1996 by the 2 letter code in the serial number, but there are only five digits (it looks like there could be one that's faded away over time, but it doesn't feel like there's anything that's worn away. I've tried to confirm that it's a 900 by using the Weber support site, but the site says that there should be more than five digits after the two letters. Maybe it's because the grill is so old. Any help would be appreciated.
