Why not rebuilt your original Alternator?
Or is it damage beyond repair?

See if they have one for a 94-96 impala.  Better alternator all the way around and 140 amps with a lot more at idle

If you're stuck any 1 wire alternator will work. A 105 works fine also in a pinch. Even 1 off a front wheel drive car but you may have to ''reclock'' it .Cars like a buick ultra have 120 amp too.

Only issue I have with the 94-96 Impala 140amp alternators are not being able to use the rear support bracket that bolts the assembly to the manifold stud.
You're OK, As long as you're running HR Parts Poly engine mounts, but if you are still using a ratcheting strap to minimize engine movement then you've got a concern as the extra stress / torque over on the unsupported alternator assembly could lead to an early demise.

I quit using torque straps after it broke the ear off the end of the accessory bracket.  Seems the bracket was not engineered to hold the torque of a decent engine when the tires stick on launch.  That was about 25 years ago.


I remember others about the same time learned that lesson  :rofl: I later went to a single poly mount.
