Two questions actually.
Shaft broke approximately 8″s above the adaptor.
2. – Do sell shafts with Opti-fit already installed?
You can remove a broken shaft from an adaptor tools and experience. You would need a graphite shaft extractor (GW1009 or MA2007), and OEM adaptor saver kit (GW0130) and a heat gun. The biggest challenge is in saving the ferrule that is on the adaptor. It is plastic and susceptible to heat. We do sell replacements for those if it does get damaged in the removal process (BB9096 is the ferrul code). We do sell the adaptors and yes, we can install adaptors on shafts. cost is the price of he shaft, the price of the adaptor and $10.00 for installation. The Opti Fit adaptors can be found on our website here:
Hope this helps.
