Yes it will work.

Also the cracked joints on the A/B sometimes the connections get really bad, especially when people keep hitting their compact with the soul of a shoe and keep running it.

The Joints not only crack but they carbon up and fry as well.

So not only use vacuum desoldering, but scrub the pin with wick and flux to clean it. Before Soldering it back up with 

fresh 60/40.

You could also desolder the whole header, and use a dremel (stone or wire wheel) if you want to be extra thorough.
