In all honesty, you probably should have just saved your money.
It will serve nicely as a get-some-points item at a Concours where originality matters, and will fit nicely in the round recess in the rear tub.
BUT YOU SHOULD NEVER INFLATE IT !!!!!
Do not even entertain getting an air canister to allow the use of that spare. Do not ever fill it with an air hose.
If Oz rules demand you have a spare and demonstrate its serviceability, seek out one of the later-model car spares - the ones that look like motorcycle tires.
The original spare tire's safety was at best questionable when they were new. That tire is now over 35 years old.
Clean it up nice and pretty, put some wax on it, and leave it home in the garage unless you are showing the car.
What to do for a spare? Most of us here carry a cell phone, a AAA auto club card and if really paranoid, a tire plug kit and some fix-a-flat cans or small 12 volt compressor.
