Sounds like real trip before the trips begin!
Getting the correct info on things is easier than it used to be but finding the direct route to them can be a real hangup, so maybe some links to get you to those which I find useful?
There is a "parts catalog and it can give some number if you get down to ordering parts but one of the real value can be in seeing the exploded drawings to locate how we might get things apart?

Hope that adds a bit of sunshine to what can be a long trek??
Come back and give us lots of reports as you get into the project. I always like to set back and see other people work!!!
Best of luck to you!
