340 Static Compression Numbers and Test Procedure

So the TC only had the drain plug ? I think the TC weight would be on the front of the TC but someone else may know better.
Forgot about any tray in there!
The ones I have seen have been located on each side of the drain plug! Thats why I took that shot clearly no weights around the plug area.
