Below is a wheel calculator that I use. Those recommendations for the front are spot on if even a bit conservative as it will only put your wheels out 4mm more than the stock set up.
Their recommendation for the 10" rear is a bit aggressive as it will put your wheels out 22mm more than stock.
Their recommendation for the 11" appears way too aggressive as it will put the wheels out 29mm more than stock. By most accounts, about 18mm more aggressive in the rear will make your wheels flush. 29mm will likely have them sticking out from fender.
