2002 v7 xc alternator

[spag]

My V70's alternator looks to have failed, just before I got home the car became sluggish and several dash lights came on, the car turned into the driveway but couldn't drive up the incline... after shutting it off it wouldn't start again... an hour later the car started and I hooked up a multimeter and could see the voltage steadily dropping.

My Alternator part number is 8622786, it's a Bosch. Are there other alternators that are compatible with my car?

I went to the volvo section of the upull it yard and all of the cars there (2001 s60, 2002 v70, and 2004 s60) had 8676498 bosch alternators in them.

Will this alternator work in my car? I brought one home and they look identical... can i remove the voltage regulator on mine and install it on the this one?

Thank you for your help.
