I contunued with the hold down buttons for the TCW. The heads on the #10 screws were too large to allow the battery to sit in the place it needs to so I turned down the heads on the screws.
When I installed the buttons and checked out the fit I found the fit was too close and tight. I had to once again remove the buttons and modify them again. Finally they got to the place that the fit was a slip fit and there is no play vertically or horizontally. I put the front screws in place to lock the buttons where they needed to be for sliding the battery in place.
That will save a lot of work and heartache if the TCW Standby battery needs to be removed in the future.
