I'd turn it around and tow it backwards. The TR-7/8 folks get downright adament about this, so that's what I do with them. I also tow backwards when I'm going to be pulling for a while, or the vehicle has been sitting for a long time (and the transmission bearings would be dry).
Lash the steering wheel tightly! Do not simply count on the ignition switch lock.
Personally, I usually use two ratchet straps, one on each side of the car, going from the steering wheel out the windows and down to the frame. Lock the hooks of the straps on opposite sides of a steering wheel spoke down at the 6:00 position. You may well be towing slightly crabbed this way, but the steering will not be wiggling.
