Double-Bushed Guide Rails

[William Monroe]

I've never rebushed the S&S double bushed guide rail.  I am wanting to keep
it double bushed for hysterical accuracy.  ;-]

Any tips/procedures to help?  I'm assuming standard bushing cloth works fine
for the inner layer, but what should be used for the outer?  I'd really
appreciate input on this one.

Thanks,
William R. Monroe
