I have a couple questions on the rear axle in my '55 3800.

First off, what name does everybody call it? 10 bolt, 12 bolt, 14 bolt, Ford 9", Dana xx?

Second, how much abuse can this axle take before stuff starts to break? Not saying that I want to break, just curious. Is it as strong as a 14 bolt from mid 80's K series trucks?

I'm an offroader, so these are just things I like to know.
