fender braces?

im trying to track down some of the more troubling rattles in my truck and in doing so i realized that i never re-installed the fender braces. i dont have any of them which sucks but i can track them down but i dont remember how many there were or how they install. its been a while. anyone know where i can find a diagram of how many and where they go?  

the gmpartswiki site might have the illistrated parts book on your truck...  

thanks guy. i will check it our right now.  

i found a book called an assembly manual that has exploded views of every part on the truck. its onliine for 30 bucks. im going to check out a local book store to see if its cheaper. the reviews say it was made for the assembly line and not for public use so it isnt set up as you would expect. no index or anything. its all in there but you have to search through all the pages to find it.  

i got the assembly manual on cd-rom and its awesome. i ordered all the braces and will start installing them when i get back home in a week.
