My suggestion to prevent it from being moved is place a BIN price to the auction. You can either set it ludicrously high so it's irrelevant or actually have something in place for if someone wants it right this minute.
I say this as I have reported a few "auctions" if you want to call them that, and they were left there as there was something like Bid in the post despite it being a locked thread, and having a set price. You could also try PMing
malevolent,
cyrus and
hilariousandco to request permission/state your intentions.
The other option is to have a locked thread here that you bump describing the parts and pointing to the auction, seems unnecessary but should be a valid work around.
Good luck
