Got one for my 07 Z71 from my dealer - make sure, if you do decide to get one, that you specify that you have the power liftgate option or not. Makes the difference because there is a difference in size. Didn't know this and got one cheap off ebay - didn't fit cuz I have the power liftgate. Returned it and got the proper one from dealer.
Not very impressed with it though compared to the one I had in my old '97. This one is very flimsy and rattles alot. Mixed emotions for spending about $100 for it. Make sure, if you order from parts department, that you get the better price. Initially wanted to charge like $140 but after showing my disappointment, they brought the price down to just below $100. Good idea to make friends with parts manager - will give you a break on prices.
