You have to be even more careful with PBT MY sets, in addition to the stepped caps lock, 1.25 mods due to the offset stem, spacebar... all of the stabilized keys may also be useless on MX boards as they can have integrated stab clips that don't work with Cherry MX stabilzers. $40 is steep for a used MY board with a lasered set. You could have probably gotten a G80-8200 for a similar price. Not only would that not have had the keycap issues, but you would also have gotten an MX board as well to use or harvest the switches from.
