In response to an inquiry from YouTube viewer Larry Ryba - here is a series of pictures and information regarding my customized Peavey Predator.
Special thanks to my brother-in-law, Tim, for sharing his impressive guitar-gutting knowledge and making this project possible (he's the one with all the tools).
Here's what I have modified on my USA Peavey Predator:
I'm a big fan of GFS parts and highly recommend them if you're looking to modify your guitar.  I replaced the pickups and selector/input jack/pots back in 2010 and didn't document that but when I replaced the tremolo and tuners in 2011 I took some pictures.  Hope this is helpful:

I had to drill out a little more space in the two outer 
holes to install the tremolo. | 
  | 
Then I hammered the posts that came with 
the tremolo into the drilled out holes. | 
  | 
Typical install of the springs - I only attached 3 
because that is my preference. | 
  | 
| Tremolo installed. | 
  | 
| Unscrewing the old tuners. | 
  | 
I also had to drill out a little more space for 
the new tuners. | 
  | 
| Tightening the tuners in. | 
  | 
| Tuners installed. | 
  | 
| Before. | 
  | 
| After. | 
  | 
| Then I scraped off the "Peavey Predator" logo | 
  | 
My friend designed some options for me to 
print out on transparency paper. | 
  | 
After cutting out the logo I picked out, I used 
Mod Podge to apply to the headstock. |
