Canon PowerShot SD750 Button Board Replacement

My brother's camera got chewed by his german shepherd, and dropped in the water.
The round button board that is used for scrolling through pictures was stuck scrolling.
Attempted to dry and clean the unit to no avail.
Found a replacement board on e-bay and replaced it.
These are the step by step instructions on how to do it.

This is my first posting, so flame on.

Assembly is the reverse of the removal.

Note the screw colors. Black on black, silver on silver.

Dont force anything. If its not pulling out, look around and double check all tabs.
