As far as I can tell, all the physical ability scores (str, dex, con) are belts now.  There is the belt of physical might, which lets you pick two physical scores and get +2 to both (for 10k, also +4 and +6 versions), or the belt of physical perfection that gives a bonus to all three.  I'll let you "convert" the belt you've got into one of the upgraded belts-as-tattoo for the difference, though.
