Swap my RH bevel gears for your LH gears as seen in pic .

I seem to have a lot of brand new metal main bevel gears as seen on the RH in the picture for the MB / BF / Wild One , Frog etc and no LH ones as seen in the picture . Has anyone got any LH gears to swap for my RH gears as shown in the pic ? - maybe 4 or 5 or w.h.y . ?
