oh-oh, debris!

Now, half drunk, let me ask for input. How do we proceed?
Have another beer. Never leave a job half done.
Tomorrow, start pricing rebuild kits and looking up videos- they're not bad to do, but the first time is always the hardest. You'll have to tear it down to find out what other parts may be needed in addition to the basic rebuild kit. If you need parts shipped from the US, the sooner you find out what they are the better off you'll be.
