Check out Bill Silvers piece on the VJMC site. Read it several times and you will see what you need to date your bike I too would lean towards a late 65 or early 66.
About the only thing there two bikes have in common is the air in the tires!
All jokeing aside there isn't too much that will trade off. That said I will admit to useing a Dream clutch lever on my 68 Suzuki! So you never know what you could use somewhere else!
