My son wants an original Floyd Rose Locking Tremolo, he's rebuilding his guitar. I am willing to get it for him, but I don't know exactly what to get. The nut sizes are confusing the hell out of me! I found this website, but it makes no sense to me at all

what do i measure on his old guitar? the neck itself? the old crap that he took off? I only have 2 weeks left, can someone please help me get the right stuff??

If you can get the brand and model of your son's guitar, we can look up the nut width online for you and find the Floyd nut accordingly. Great choice in purchase though Original Floyds are amazing, and he'll love it.
