Brake line removal/repair/replacement (something?) help

[rhock99 at epix.net (Ryan H)]

Awesome, thanks John!
So, can anyone confirm which one of these UNIONS would work with the stock male connectors?  Or do I have to buy new male adapters as well?  It says 3/16" pipe size for most of these, would that be correct?
