I'm toying with the idea of replacing both a 740 sedan and Dodge Dakota P/U a single 740/940 Wagon before they they become harder to find. I was wondering if one of you wagon owners could be so kind as to give me the following dimensions of the cargo area? (with the second and third seats stowed)

1.) Back of drivers seat to the tail gate (seat slid all the way back) = X
2.) Width between rear wheel wells = X
3.) Height of open rear hatch = X
4.) Width of open rear hatch = X
5.) Approx how high above the floor must you come in order to realize a width that is either equal to the hatch width, or at least 48" = X above floor

Thank you very much.
