get a rebuild kit and do it yourself
just buy a reman MC is fastest and safest,IMHO
it sorta like a clutch slave cyl to rebuild
2 bolt or 4 bolt ?
you can hone the bore with a wheel cyl tool if you get the over size kit and mic it
not much need for that kinda stuff any more with all the reman stuff around
if its a 4 bolt MC I allways adapt it to a alum 2 bolt MC myself..
