Seat Belt Question

I haven't been paying much attention to rule changes. A friend of mine told me tonight that the rules regarding seat belt (harness) expiration had been changed and that the 2-year limit has been modified by ET. I have searched and can't find any information. Is this true? Mine are currently expired (2-years past DOM) and probably wasn't going to race this late in the year if I had to buy new ones now. My car will run 10.60, am I good or do I need new ones? Thanks. L8r
