Belt Tensioner & Idler Pulley Bolts

Does anyone have any idea what size the bolts are on the belt tensioner and idler pulleys, specifically on a LB7? I have looked everywhere and cannot find the specs. I am replacing them this weekend and was wanting to replace the bolts as well.

You can find out about all the parts for your truck by using your VIN# and going to a GM based parts lookup, like GMPARTSGIANT.COM, and find your part.
