Towing Question

[lx450user]

Hi I just became the owner of 2 lx450's One lx450 is running and the other is no going to be licenced so I need
to pull it to my house. I was thinking about if its possible to put the
2 front wheels on a tow dollie type trailer with the 2 back tires on
the ground and tow it about 70 miles on I-75 with the other lx450.
What do I need to do to be able to tow it this way. Is there a place on
the gear shifter to take it out of all the gears so the back wheels will
turn freely, or do I have to take the driveshaft off . Thanks for your help steve
