BB/Crank spindle help

Got a new bike frame and I was looking to use my old crankset. The bike has a BB86 shell, but currently has bearings for a 30mm crank installed. My old crankset (Quarq power crankset so it’d be nice to still be able to use it) is SRAM GXP but it’s for an old 68mm wide BB30 and has the 3 bolt direct mount. Any idea what crank arms I can swap to that have 3 bolt mounting and will be long enough for the BB86 width?
