Here is a short tutorial on making easy stealth drives for a TJ07. It is from my worklog.
You have to remove the stock faceplate from the dvd drive and leave the face plate on the front of the drive tray. The stealth plate attaches to the front with strong double sided tape and the button pusher (don't know what else to call it) also attaches with double sided tape.
The hardware to push the button came from the hard drive mounts so depending on how many HDDs you plan to use you can get the hardware from one of them. Make sure that the opening for the button on the front of DVD drive is big enough for the screw to fit through. once on the screw can be adjusted to make good contact with the button.
Bend the flange pieces with the screw holes on the metal face covers to snap them off and put a strip of tape on. Attach it to the drive with the drawer closed otherwise lining it up will be difficult. If you run into clearance issues bend the bottom edge of the plate upwards to make a 45 degree angle (You may also need to trim the metal on the corners of the flanges to improve clearance. and then it should line itself up when the drawer closes.
