Can someone FOR SURE tell me the ARP Part Number for the harmonic balancer bolt for an LS2 2005 Corvette?

Sites are showing different things because I think some sites don't understand the C6 2005 Corvette has the LS2, and I don't want to make a mistake.

Even ARP web site doesn't show an option for 2005 Corvette Harmonic Balancer bolt, not sure why. I go here:

https://arp-bolts.com/kits/Make.php?_Make=303&_EngModelID=426

...they show no Harmonic Balancer bolts at all in the lists that I can see.

Google not much help because getting inconsistent answers. Already frustrated that the whole steering rack (maybe more) needs to come out just to replace this bolt and maybe balancer because it worked loose.

Thanks.

ARP lists two: #234-2504 w/ UHL 5.225", and #234-2503 w/ UHL 4.325".
Which length is yours? I think that is the deciding factor. Not sure there is any difference between Gen III and Gen IV crank bolts. Both are the same thread size.

ARP's are reusable. Plus that's what the OP wants.

Yeah, that totally makes sense. The longer one is for the dry sump engines while the shorter one is for all others.
OP, you have your answer!

Thank you all! If this turns out to not be the case I'll post it here.

Any TTY bolts (aka non-reuseable) I try to avoid because I typically own my cars for a long time and don't want a one-time-use bolt to deter/prevent me from popping something off to check it out in the future (same with heads).

Also, I might someday cam this thing, or I might need to pin this sucker since the problem seems so incredibly common. I just don't want a throwaway bolt here that I can't pull out any time I want to.

PS - ordered the bolt, cheapest place I saw was Advance believe it or not as they had a 20% off something or other on their web site and ships free over 25 bucks I think. Jegs/Summit/whoever seems to want at least $9 shipping.

Thanks again all.
