Awesome much appreciated, i must have an off rim size seems like every thread ppl have 17inch stock ones. I really can't wait to hey some height on this truck

Vast majority, the 17" were optional and 16" were standard 2002-2006. Later it was 17" were standard about 2007 and later and 20" were optional.
I drive on 16" and had BFG 285/75-16. I had to do some rear inner wheel wall plastic trimming. Plus the front, if I turn to tight. I will rub a little. I'm not lifted, just stock 2003 - Z66.

17s came with the Z71 and Z66 packages on the first gen AVs.
