Space Combat: Random damage locations only? Targeting rule?

[James]

I was wondering if there are rules anywhere about targeting a ship's system. Rolling random damage works fine but I would love to target say the m-drive and destroy it setting up a ship to be boarded.

If there is no rule in the book are there any house rules that people use to do this?

I was thinking a -2 or -4 to hit then you choose the system, but I want to know what would be fair.

Th pirates of Drinax campaign has rules on targeting ship locations, if i remember you have to be in close range or less, and can modify your location roll if you hit. As its a free download on this site i would check it out.
