Vantage slipper clutch

[Brewskie]

I've stripped the spur gear on my Vantage an tryin to take off the little grub screw where the main drive shaft connects rears to fronts to the slipper clutch (part number FAST123) an cant for the life of me find the right Allen key to fit, does anyone know?

FAST123 is an M3 screw, so you'll want a 1.5mm allen key or hex driver.
