https://www.titleist.ie/teamtitleist/team-titleist/f/golf-clubs/21270/how-to-id-an-oem-910-913-driver-adaptor Just curious. I picked-up a RIP alpha 70 driver shaft from ebay. Of course, it didn&amp;#39;t have the &amp;quot;Titleist&amp;quot; hologram on the shaft, but that may have been removed by the previous owner. I did notice however that the serial number on the adaptor is differenten-USTelligent Community 10https://www.titleist.ie/teamtitleist/thread/93691?ContentTypeID=1Fri, 17 May 2013 18:04:21 GMT9ab519fc-5311-4952-85cd-0a0ceffb73fb:47d62475-d392-4adc-8892-e355b6f0b5b9Ken W<p>Dave, Most of the identification is common sense. Examine your adaptors closely. Are the ferrules the same length and diameter? Are the numbers and letters on the SureFit the same size, color, and font? Is the black paint, the threading, and the screw identical to your known OEM? Major aftermarket adaptors will use Roman numerals etc. and will look slightly different than Titleist SureFits. Looking at the small details will usually reveal whether an adaptor (or counterfeit clubs for that matter ) is authentic OEM.</p><div style="clear:both;"></div>
