Cyber White Navs... hrm... not sure how they mount up, but when I did my Angel Eyes I didn't remove the stock brackets.
SSE14, I believe you should easily be able to install those navs w/o major changes to the stock bracket. Unless they mount really funny.
Here'* a link to a bunch of photos when I had my Angel Eyes installed.
I hope that helps...
If you're still confused, can you snap a few pix of your cyberwhites and the mounting pieces... and I'll try and figure out the best way to mount them. I always prefer to leave as much stock if possible, incase I ever want to go back to org.
