1939’ Deluxe 2DR Sedan

[ssffnomad]

Hi Guys. Dreaming about a OD trans.
) Does a 39’ Coupe & a 39’ Sedan have the same floor pan in front of rear axle ?
) I measured 17” from the rear of Torque Tube forward to where the Floor steps down. I tried looking up Mitchell specs. Anyone know how far forward from the Torque Tube a Mitchell gear box is ?
Thanks, Stretch
