Does anyone know if they sell the clutch reservoir separately from the whole master cylinder setup? I was looking through the 2004 part manual for my car and they only show it as a full system. I noticed the last time I drained and filled mine that the reservoir was starting to get pretty brittle and I'm afraid it's going to totally crack one of these days. I could probably find a generic aftermarket one that would work, but wasn't sure if anyone had ever replaced theirs before.
