Is this the correct bolt?

If either is wrong please point me in the right direction.
If you do anything, I would highly suggest to change the FRONT Seal. It's cheap and right there. It indexes to the previous balancer so you want to change it to prevent any type of slow oil leak. Also, if you go with the SFI rated balancer you listed it's amazing. I actually just installed it on my 06 Z51 the other day. Pick up some of that Silicone (RTV) I listed. You'll need it to fill in that keyway unless you plan on using that to key/pin the balancer. Oil will drip out of it if you don't plug it up. Just a little on there before installing and then right before you put your ARP bolt on squirt some in to make sure it's sealed off completely. Also, don't forget to take your measurement of the balancer depth before you remove the other one to make sure the new one is seated all the way. Will need that measurement when installing the new balancer to make sure it's seating in enough to line up with the belts.
