I'm not actually for postive sure what my height numbers are myself. The rear measurements change depending on which tire I am running at the time. One set of slicks is 1" taller and the other is 2" taller than the radials. I like to say I have a "just right for me" drop

. Here's mine.
Rear....31x18.5x15 Hoosier Pro-Street Radials
bottom of opening to axle center line is 12 3/4"
bottom of opening to floor is 27"
Front...P255/6OR-15 Seiberling Falcons
bottom of opening to axle center line is 11 3/4"
bottom of opening to floor is 24 1/2"
