I bought a set for my 2500 that said 6.6LLY
Here is a link to the pics. http://www.dieselplace.com/forum/showthread.php?t=29683
They are a little pricey, but I think they are worth it. They have a variety of colors and all kinds of patterns. When I got the stickers, there was a GM logo on the packaging and it said the fonts and colors were approved to be the same as the factory lettering, just different designs and colors.
I did the online order and they were shipped in a decent amount of time.
The part I liked, they came with really good instructions on how to get the old stickers off and how to put the new ones on. Follow the directions and they look better than the factory could put on.
I'm waiting for spring so I can put another set on my Avalanche..
Hope this helps.
