where'd you get it from? The manufacturer should be able to provide you with a template. If you have the tower, the installer should be able to use the tower to draw a template or get the pilot holes in the correct location.
Or, you could try printing out this template I found using the magic Google. It's for a 3" tower, and see if it matches up to your tower. I would think they should be mostly standard. After printing, it did measure a correct 3".

Sometimes when I reflect back on all the beer I drink I feel ashamed.
Then I look into the glass and think about the workers in the brewery
and all of their hopes and dreams. If I didn't drink this beer, they might
be out of work and their dreams would be shattered. Then I say to myself,
"It is better that I drink this beer and let their dreams come true than
be selfish and worry about my liver."
