A few days ago, I replaced the brushes in my alternator to fix my intermittent lack of charging issue. I used this one for my 1997, other models have a different part number.
Toyota Alternator Holder - 27370-35060.
Yesterday I pulled the front seats from an E90 (2006 BMW 325i) for a future swap project. All manual adjustments, so hopefully it should be only figuring out mounting and not all the wiring that others have done in the E90 seat swap thread.
