We were able to remove Aussie7's spacers on Monday, some heat was needed.
Going through our records, it seems these were originally installed 2.5 years ago, there was no anti-sieze left on the lip with confirmation from the owner they haven't been touched since the original installation.
With that being said, it would be good practice to possibly include spacers in on a regular maintenance schedule, reapplying anti-sieze on the hub lips annually (and removing any new surface rust), just to be on the safe side. Doesn't hurt to check them out every once in a while.
