a regular spaced DMZ on a strat will be WAY WAY off. even the F-spaced DMZs fall short on the wider vintage spaced strat trems. i have 3 strats with vintage style trems with F-spaced DMZs in them and each of them are off a bit and don't line up perfectly so i'd be scared to see how off a regular spaced hum would be.
however on a MIM strat with the narrow spacing you may be able to get away with it.
