Alternator pulley question

[Andy_w]

Hi guys,
I am looking for a new alternator pulley for my 1.8t and have been looking on eBay.
most of the items on there are listed as fitting 1.6/1.8/1.9tdi and 2.0 tdi.
Are they a one size fits all pulley, or should I be looking at a model specific item?
Thanks in advance
Andy

Thanks for the link, I have had a look and they are diesel specialists. My car is a 1.8T.
