Towing question-brake update

First of all, thanks to everyone who gave advice to my spongy brake problem. It was caused by the Metalmaster pads (used for a DE) eating the rotors away more at the outside edges than the inside, hence rocking the pad and causing mushy brakes.
Question...I'm going to tow the 86 Carerra on a flatbed, and am looking for a tiedown procedure and points. Thanks in advance...
