Dont know.Had the M.C. & booster left from a halfcut & installed it all myself.

If u read thru the DIY i posted,I think he gives a bit of an idea on parts cost,cant remember.
Think it goes something like $120 for parts to rebuild yourself or $240 for new M.C. complete.A mech would prob charge bout 1 hr labour,I guess for changing just the M.C.(bout $80-$100)
