So I'm doing my first conversion, a GX35. I picked up the electronic conversion kit from BCMA and have worked through hacking off all the extras. I'm getting ready to put her together when I realized I don't have a Woodruff key for the prop adapter? Not to sound super stupid [], but I didn't really even know what a Woodruff key was until I looked at the two matching grooves and assumed I was missing something (did a bit of digging on the net and figured out the missing link). Anyway, If there was one on the clutch, I probably tossed it. Does any one know what size key I would need and where I would buy one. Thanks much, Dave
