Front and Rear Propshaft bolt?

I am trying to find out what size the front and rear propshaft bolts our for our trucks. I took my shaft out and however at GM that decide those star bolts where the ticket should be shoot. Well if you guys can tell me what size they are that would be great I am going to put the shaft back in and need to know what size the front and rear bolts are that way I can get normal bolts with good heads into the shaft.

Thanks as always guys

I went to alot of trouble to track down the 10 & 12 mm bolts w Hex
heads. Had to go to a Bolt/Nut shop and order them. Now looking at
the huge head size, particularly on the 12 mm bolts, I'm wondering
if they will fit in. So, while I was ordering GM stuff from Dal, I ordered
the Male Torx bolts from GM and they were cheap. I'll see how they
all fit when the car is going back together.

The head size of the rear bolts makes the torque specs practically useless unless you have a torque combination wrench... Having someone step on the brake while you install the bolts with Loctite 242 threadlocker (blue in color) has worked well for me with no problems.
