Glad you survived.
Here's a tip, when you remove the o-ring and spacer loop the o-ring through the spacer and pull tight, then when you go to replace the spacer the answer is in front of your eyes.
There's no madness in method.

One step further I clip the handsets together with the spacer and oring hangin on the clip can't miss them then.
