Broken Tabs, help opening Performa 6400

[NiceToCats]

I would like to swap the orginal HDD in this Mac, but I can't get the front off. The 2 tabs that instructions show to push are broken off, and I can't find a clear picture out on the web of what those tabs actual do. I'm open to suggestions...

There are tiny clips on the sides of the face plate that lock it to the side panels. There are also hooks that attach it behind the drive bay at the top, so you have to get the side clips off with a spudger and hinge it upwards.
