The Alternator from a 1.8 or 2Ltr Sierra is a good one to use. Most parts stores will offer a refund if you give them the alternator from your donor car in exhange for a refurb'd unit.
The fixing plate supplied by pilgrim will allow you to afix the alternator in place. The tensioner bar is then secured using a lower bolt fixing from the water pump. If you wish I can take some photo's over the weekend...
