Does anyone here know what the track center spacing measurement is on the EZ Track Crossovers such as product 44137 for example?  They would work great with the 33.25 and 35.5 inch radius curves if the spacing is 2.25 inches, or with the 26 and 28 inch radius curves if they have a 2 inch spacing.  Or are they something different that those?  Any info is appreciated.
