2007 Honda Rancher 4x4ES Parts interchangeability

Greetings all. I am hear to share a lesson learned. I purchased a 2007 Honda Rancher ES from an online auction. When I got it home I found that it had no brakes. Well I mean to say that the cable on the rear brake was broken so the back brakes may work but on the front there were no brake or calipers or master cylinder or brake handle. Yea I know I should have seen that in the pictures but I was actually bidding on a tractor and this was an impulse bid, is there such a thing? Well I am looking for a wrecked or blown motor one that I can pull all the parts I need but haven't found one yet. So here are my questions.

What model years are interchangeable with the 2007 Honda Rancher 4x4ES?
Where is the best place to buy parts?

Thanks for reading and I hope my mistake helps someone else from making the same.
