Oh dear, as u can be seen its a D1 200 series steering wheel and part numbers in that link, therefore the link is incorrect for you.
The correct information is:
So as you clearly state u have a 1998 model there two options depending on your vehicles VIN, so take your pick, they seem to be available still.
NTC9939LNF upto VIN WA773562 at around £10
QTN1002060LNF from VIN WA773563 at around £20
Better to get the new item I would think, as it's something that is a central feature and not to fall a part when u need it
