I couldn't find anything on line. You could call customer service at Project X and have someone give you the specs and/or the logical replacement. It apparently was a real-deal shaft through Titleist, so if you follow e-Bay or some of the other used club sites, you may find a 910 or 913 driver with that shaft. Since the driver shafts from the 910 are still interchangeable through the TS series you can buy the used club and resell the head after stripping the shaft.

Dustin, I have that shaft on my 910-D3 driver, and the Project x-8c4 on my 13.5 fairway wood. The weight of the 7c3 is 73 grams, the 8c4 is 82 grams. I forget what the torque number was but I think both were around 2.5.

I'm not sure launch and spin numbers were even available in 2010,so if I had to guess,id say launch is low to mid.

Hope this helps
