Installing internal SCSI CD-RW drive in b&w G3

[sidereal]

Hello,

I just bought a Yamaha SCSI internal CD-RW burner for my blue & white G3. I'd like to either replace the stock drive or put it the open (zip) bay.

Problem with the zip bay is that it's too narrow for the drive so that's out. Which leaves me with replacing the stock (IDE) drive. I have an ATTO single-channel SCCI accellerator card, so that's fine. But I can't figure out how to remove the stock drive. There are two screws I see at the bottom of the CD drive's bay, but I'm not sure if that's it and I don't want to go (sorry) screwing around with things when I'm not sure. The Mac manual was no help.

If anyone can help me out or point me in the right direction I'd appreciate it.
