Rear Shock Bolt size and where to buy

[SPASierra]

I swapped the Ranchos for Bilstein 5100s a few thousand miles ago.  I just got back from a 1400 mile trip to TN with my wife, and had a rattle while we were gone.  I couldn't see anything obvious at a quick glance, but a check underneath this morning shows that the driver side upper rear shock bolt has backed itself out, and the shock is resting on the spare tire.  

 

Does anyone have the size for the bolt handy?  I found a part number on gmpartsnow, but it is discontinued.  My Google-fu is failing me, and I just need to pick up a replacement bolt.

 

Thanks!

Just go to a dealer.

That what I ended up doing.  For posterity, the part number is 11589357.  They come in a 2 pack and dealer list is $14.03/ea.  The parts guy at my dealer charged me the shop price of $10.07/ea.

Torque spec for that bolt is 70 lb-ft. Use a torque wrench so it doesn't come off next time.

If you're in an urban location, industrial supply shops are a cheaper source for fasteners than the dealer. I've never dealt w/ Fastenal, so I can't say how their inventory is. I have heard that Grainger can be pricy. As a retired tool & die maker, I have a couple of shops in the nearby city that can access.

Thanks for the info.  I had thought about trying to get over to Grainger, but the dealer dropped the price enough that buying from them was fine.  They will be in later today.
