Replacement left handed driver shaft

I'm a lefty and had the same problem a couple of years ago when trying to get a shaft for a Callaway driver. You can use a RH adaptor but the settings won't match what is in the adapter. Here are my notes that I got off another forum back at the time I was looking into this:

The lie angle stays the same but the loft that you'll be setting the club is on the reverse side of the club. So, S (Stated loft) is +1, +2 is -1, +1 is S, -1 is +2.

So,
D (Draw setting) -1 = D +2
D S = D +1
D +1 = D S

Otherwise you can try to get a LH adapter on eBay or give lefthandedgolf a call
