What should I check before ordering a new door lock gearbox case?

The most important measurements are the backset (the distance from the centre of the handle spindle to the front of the faceplate) for this item either 35mm or 45mm and the lock handle centres (the distance from the centre of the handle spindle to the centre of the barrel) in this case 92mm. Both measurements should be checked before ordering to ensure compatibility.
