CB 750F Mainshaft Length

[Leatherneck 1967]

Hello, I am near completion of a 1976F CR Replica. I purchased the bike near completion and is having trouble with installing the clutch. The mainshaft spline is approximately 21.00 mm and the inner and outer basket is the same as a 750K SOHC. The mainshaft spline is approximately 25.50 mm on the K model. "Question", What do I need to install a clutch system on the bike that has a mainshaft 4.50 mm shorter than the K model with a 25.50 mm spline. Any assistance would be greatly appreciated. Thanks

Got it figured out and clutch is working well. The 750F has a small spline washer behind the basket. The K has a large spline washer, once the correct washer was installed it works fine. Thanks
