2015 Tundra SR5 Std bed 2WD - Center of Gravity

Can anyone please tell me or lead me to where to find the CoG of the vehicle front to back? I found something here. It says that it is 60.8in rear of the center of the front axle for my model. The problem is that I think the spec is based on a 4WD model and not 2WD. I tried to locate a service manual and no joy there either (even after checking Helm.com).

Tried searching the forum threads/posts too, no joy there.

Endgame:
Trying to get proper dimensions and especially placement of a new 2 post lift I plan to install and want to get it positioned in the stall correctly. Getting the truck CoG is key to being able to dial that in.

Any help would be greatly appreciated.
