EMD F7A coupler replacement

[Metsfanrich]

I'm trying to replace the short coupler at the rear of the locomotive, but I can't figure out how to remove the old coupler? Any suggestions?
Thanks in advance.

It should be held in place by a screw or clip. If it's a clip, put a small flat head screw driver on 1 side of the clip a twist the side off. Then remove clip. Clip will look like this :
