2005 5.3L Chevy Silverado oil pump, timing chain, water pump, and ac

Water pump failed, so I decided to change the oil pump, timing chain, and A/C compressor as well. cost about 500 buck for all the parts and gaskets. i bought name brand parts form amazon, rockauto, still had to use Autozone and Walmart for for all the small stuff. It took a lot of time, the hardest part was removing the sprockets and harmonic balancer pulley. I also could not remove the oil pump with out removing the oil pan but that turned out not to be all that hard.
