The Modolo levers were patterned after Campagnolo, and the 919 hoods work well on Campagnolo levers. Whether these Dia-Compe hoods would also work isn't clear. One of the reviewers on the Velo-Orange site mentions that they work well on his SunTour levers, but dosn't mention a specific model. Dia-Compe made SunTour's brakes and levers, the ones they made as SunTour "Superbe" are a close copy of Campagnolo, and I've used 919 hoods on Superbe levers, so there's a chance it would work. Dia-Compe's own Gran Compe levers are slightly different shape from Campagnolo/Modolo/Superbe.
Otherwise,
Boulder Bicycle has hoods that would work, but without the nice anatomic shape of the 919 hoods.
