The cornor broke off the housing assembly and instead of rigging up a stablizer, i simply took the part number and ordered a new one.

I too the front knob off the timer, took the screws out of the top of the panel, unpluged the timer and plugged the new timer in, removed the old timer one screw and pulled the old one out, reversing the process to get the new timer mounted, replaced the panel, replaced the timer knob and finished the job in about ten min.
It is not rocket science, well I confess, I once worked on rockets and their components, so it was real easy for me.
