This is a Bosch-remanufactured 80A alternator part AL157X.
I bought it for a B21 project I've been working on as I wanted a higher output alternator but I don't like the fitment on a B21 so I'm selling it. It will fit most B230 Volvos, including later 240s, 740s, 940s, just check your car first if you're unsure, some have Denso alternators instead, which look different.
A new voltage regulator is included as part of the alternator.
I believe the alternator comes with a 2-year warranty that started yesterday.
This cost me $288 + post new from RockAuto.
