Check out
www.boschusa.com. But be warned. The first one I installed went was bad out of box. The second went bad in 6 months. (given I am no master mechanic, but I have done 6 alt jobs).
Third one going strong. They have a 12 month warranty and cost about $195.00
Some people say Bosch sucks and they may be right. I was just too cheap to buy a SUB original and too impatient to have it rebuilt at a local ALT shop.
Clean the negative ground connection too. Where it bolts to the frame.
There are also 2 types of SVX alt.: 95 amp for those with ABS & AWD and I think 80 amp for the FWD/no ABS SVX models.
But I would think the mounts and therefore ALT casing should be the same size for redundancy's sake. Autozone probably gave you a Legacy or Justy Alt.
I have read of some guys here putting in 110 amp + after market alternators as the 95 AMP is barely enuff to keep the SVX afloat; considering they also installed whomping stereo systems.
I have never seen the part number or manufacturer listed of the 110+, however.
If you are willing to gamble here is the Bosch part #:
Part Number Description
AL4328X Reman Alternator MITSUBISHI; Amps: 95; Internal Regulator; 12V; Clock-Wise Rotation
Good luck,
