Using reverse to back up the aircraft may be prohibited in the AFM. An old copy of a 747-400 AFM with PW4056 engines I have states in LIMITATIONS that "Backing the airplane using reverse thrust is prohibited."

I know that some models of A310 have different towbar attachment points. I seem to remember SU A310s were the oddball ones.

Also From what I remember, the B747 had towbar attachment points on the rear of the landing gear, identical to the ones in front which could be used in extremis.

Didn't a Qantas guy overcook a donk in Damascus when he tried to reverse a 747?
