So, in the absence of any truly enlightening responses, I will say that I spoke with two acquaintances who are machinists and who do a lot of BMW work, and both independently said that if there were no obvious identifying wear patterns or marks, they'd recommend just bolting them on wherever and not worry about them.
I'm still happy to read the responses of anyone who's experienced this, but I feel pretty confident just reusing these at this point.
Thanks anyway,
