Get some cheep insurance.
Quality bolts hold your car together and will save your life.
Buy a Ring Gear bolt kit from ARP #250-3002 $29.72 or Mr Gasket #2094 $24.03
Those grade 8 bolts from the hardware store will not keep it together.

 

I used the bolts on my ring gear that have the safety wire holes in them b/c I have had them back out before. Safety wired them all together and no issues since.

 

X2. Our 3rd member was fine for years but 3 years ago we pulled it out just to take a look and 3 bolts were out far enough to hit the caps and the others were all lose. Put it back together with new bolts and locktight ( red ), ran it for a year and checked it agian and they were lose. New ARP bolts with safety wire and locktight and they were good this year and we will check them every year from now on.

 

Loose me bolts

had the same thing happen to my blower, brand new rebuild with 12 runs the bolts that hold the hub to the front gear bolts came loose, and were just starting to get the cover. now loctited and safety wired. if you cant see it, you cant check it!!!!!!!!!!! i would do this anywhere possible thats hidden.. cam bolts, rear end, blower, 2 bucks in wire beats a high repair cost.
