Attention during Replacement
This is where most people had the same problems:  couldn’t get the set depth right.  If you screw it in too far then there’s no give but too much means it doesn’t work right either. You may had to reassemble and disassemble three times to get this perfect.
Something you wish you did before removing the old screw from the old top case was noting how far it was screwed in.  taken a picture first so I knew how far to screw in the new T5 on the new top case.  Don’t make that mistake.
While removing the four tiny screws, support the trackpad on the bottom with your fingersavoiding dropping off
Turning the screw counterclockwise will loosen the trackpad.
Turning it clockwise will  tighten the trackpad.
Make sure all gaps between the trackpad and palm rest are equal.
