How to get a local, older version of Safari on OS X Mavericks?

Question

How to use an older version of Safari ( like Safari 5.1 or Safari 6.0 ) on Mac OS X Mavericks ? This StackOverflow question answers my question for OS X, except Mavericks.

Multi-Safari website doesn't load and from a google cached copy I only saw Mac OS X Lion solutions.

I'd prefer a local solution instead of using services like BrowserStack because they're just annoyingly slow...

CNET has outdated Safari versions for download, e.g.

• 5.1.7 , found via this search for Safari 6

• 8.0.6

That said, I couldn't actually install them -- running the installer seems to succeed, but nothing new appears in /Applications, and OSX won't let you delete Safari as it's "required by OSX".
