A good automotive machine shop has a machine that will hone the bushings to size and in line, (not a brake cylinder hone).
This is often considered to be a better option than reaming.
Honing it yourself, although possible, is not a good idea if you want the most possible life out of the bushings, as alignment between bushings is the problem.
Best to have an automotive machine shop do the work, either hone or ream.
