Single bolt cam...Bolt part number???

[dontlifttoshift]

Putting a a cam in a 2010 5.3. New cam is single bolt style and I have the correct new sprocket but I can not find the bolt to hold it in. The GM number of 12561283 doesn't show up anywhere in countless searches even though it is in the catalog. The bolt that was in the motor has a bunch of oil holes drilled in it for the afm and I am not sure I should reuse it.

I am really stumped here and would appreciate any help.

Thanks
Donny

12561283 is still a good number and my Chevy dealer had it in stock!?! Too cool. Worth noting is that it is a torque to yield bolt and is only good for one time.

Thanks
