Guys
The std Phantom should have the coarse spline alloy lever but the 5 speed motor over its life might have the early fine shaft fitted just check before you order
Over the years never matched up a jap lever to fit a Phantom . Suzuki one was close to fitting the very early 4 speed only
Doug on USA Ebay has both or any of the Ossa dealers
Cheers
