Tamiya Pole Trailer Help!

[TRUCKMAKER]

Does any one have a stock Tamiya pole trailer that can give me the dimension in mm/in. between the red lines in the photo, which basically is from the forwardmost lower edge of the fender extension to the centerline of the forward axle? I have 2 trailers on order but won't have them for a week. Trying to draw up plans for the project. Thanks for the help!:D
