From what I've read here, it seems it's possible to replace the timing chain guide bolt with the improved version by simple removing it and cranking in the new one. (I have a Dorman here.)
I'm paranoid that things won't line up and I won't be able to get the new one installed, not to mention worried about dropping or breaking the old bolt.
BTW I have the valve cover off and timing chain is tight so for a number of reasons I'm putting off changing the chains for now.

Use a magnet to remove the old upper guide bolt, and install the new replacement bolt. I’d still change the chain set . Have a look at the front guide they tend to break around 100 to 125,000 miles.
OK. The chains will be done soon, but I‘m thinking about other work too and it may make sense to just drop the engine cradle and do everything at once. We’ll see. Wish someone made better plastic chain guides that won’t break.
Very helpful to understand. I’m taking your prior comments as assurance that if I remove the top bolt, the guide should stay in place and it should be possible to properly insert the new improved bolt. Will be doing that today. And another HHR with just 70K miles or so soon. -signed, Worry Wart.
Moot point, eagle eye FMG caught the broken front guide! The replacement bolt is not going to help this situation, change the timing chain, balance shaft chain and tge guides and tensioners
Thanks, F.G. ! Now that you mention it, yeah! I though I was looking at some gunk. That’s kinda why I posted the pic. I don’t have any experience in there.
