I took a tape measure to it and it measured 184" from the center of the steer axle to the empty space right between the tandems.

Thats the correct way in the USA. Axel spacing and wheel base are 2 diffrent measurments. on a 3 axel tractor the Wheel base is measured from center of front axel to center of tandems. my build sheet from Mack in 1977 shows i have a 206" WB when I measured to center of tandems It indeed is 206".

front axel to first rear axel spacing has more to do with bridge weight laws.
