I'll just post what I sent to khadventures in case anyone else is viewing this
What Marshall_d said to do does not work on my housing as there's no groves or threading on the flash link or the DC800/1200 housings
kh~ and I were able to remove our flash links without breaking or scratching a thing
Below is what I PM'd to her:
_________
Take a small thin flat head screw driver. I used 1/8in wide; very thin as well.
Now with the camera lens facing you you'll see two lock points where the flash link locks in place.
You'll want to leverage the left one, below the shutter button and flash.
The point where you leverage is on the lower area of the lock point; closer to the base of the camera. Leverage from the side of the lock point, not straight up from the top. Your screw driver should be orientated so the end is pointing to the top of the camera case.
Apply a little leverage with one hand and with your other, apply a little force, pulling up on the part of the flash link that juts over the flash window of the case.
Once you get one lock out all you need to do is slide slightly and pull the other lock out.
PS if it helps to visualize, the locking mechanism consists of 2 flat pieces of plastic on the flash link that stick into the indents of the camera case.
There's no wedges or the likes to hamper you.
Have fun taking pictures
