WTB surf alternator - 90 2LT

[Ryanjury]

As above just trying to locate an anternator for my surf, the pully and cooling fan on the front somehow detached themselves and according to the alternator guys it is unrepairable. They have quoted $440 + for a new one which seems a bit steep to me, just posting on here in case someone has something lying around that is suitable.

It is from a 90 with a 2LT in it and has the vacuum pump on the back, not too sure how to identify it further, it is currently at the alternator guys so cannot do a photo..
