Well, I was hoping to get around to working on her this weekend, but my to-do list is damn long, so I never got around to it. But get this - my wife was out shopping this weekend, and just for kicks she stopped by Summit Racing (we live about an hour from Summit). She just went in there and walked up to one of the guys and asked "what one thing under $200 would give a '95 5.0-liter Mustang the biggest performance upgrade".
So she came home with a set of FRPP gears! They're 3.73, which is exactly what I would have done, since we'll likely do a fair amount of freeway driving in this car.
