If, like me, you break off your Valeo alternator's regulator stud then here's the part.

The part number is 09366 and it fits '03-'04 Disco. Price is $22.25 plus shipping.

My local alternator shop wasn't able to find anything so I spent an afternoon Googling.

They have a downloadable catalog that lists parts for other alternators as well.

 

Good to know. I bookmarked it thanks.
