three sped trans rebuild

[Rjdisi@aol.com]

I am rebuilding my BN-1's three speed transmission and have a couple of 
questions,

There are bronze bushings for the clutch operating shaft which are worn on 
one side (approx. 1/3 to 1/4 way round). Can these be replaced? If so can new 
be 
sourced?
Anything else I should watch out for?

Thanks,
