I'm facing this repair also, my clutch fluid has been dropping all summer, and I topped it up in the spring too. Just reading that other thread, it sounds like it can be done, but I'd like a concrete Yes or No if it's as simple as popping out the old and in with the new. Some are telling me it could be a leaky slave cylinder too, making my fluid level drop. I just ordered the seal, but haven't taken anything apart yet. Some guidance here would be nice!
