2nd optical drive, XPS 8700

I bought a 2nd optical drive that is the same model as the first one that came with this desktop. It's a TSST SH-216DB.  How do I remove the black plastic flat bezel on the front of the new drive and then how do I remove the bezel from the empty 2nd slot on the PC (which I assume drops down with a spring when opened like the 1st drive) and attach it to the new drive? So that when I'm done, both optical drives look the same on the outside and operate similarly.

Thanks for any help.
