Does anyone know if bravo 3 dual props will work on a Volvo dpx lowers with dual props

No. They are not interchangeable.

Where is a good place to look for some Volvo dpx props

You do mean DPX right? There is a difference between DP and DPX. Volvo DP is the equivelent of the Merc Bravo 3, DPX is the high performance duo prop setup from Volvo. Just sayin....
