Shane - Do you have the assembly manual yet? It will be helpful when looking for all the attachment points for some of your projects. On ebay or through one of the vendors. About 30.00 and worth the $$.
You will find Mar-K are the bed people. They are very reliable and helpful on the phone if needed. They also have a presence on Stovebolt.
And if you have not found the GMheritage package for your truck - find it, print or save to desktop.
Ask us questions when you have them.
