The framework where the stock latch is has a bar that goes across the front of the radiator. You drill two holes on each end of this bar and stick the threaded studs down through them. Then you take a lock washer and a nut on the underside of it and use it to adjust how high you need the studs to stick up. Then you put another lock washer and nut over the top all the way down to hold it in place. After that, some people will just bring the hood down on them and give it a little bump onto the studs to get dimples of where the studs will hit. They then use those dimples as their marks to drill the holes in the hood. Usually a plate fits over the top of the holes then that you put a lock washer and nut on the underside of to hold it in place so that they holes have a clean look to it. Also the lock pins are usually connected to these plates. Ya put the hood down and the studs should slid right up through the plates and you put your pins in and voila!

I hope that helps make it a little more clearer of what all is needed and involved in doing them.

**EDIT**
Oh yeah, and some people keep the stock latches as an extra security feature if the car is their daily driver and they don't want people getting under the hood and messing with stuff. But, some people also take the latches off for easier access... I for one would keep the latch.
