I posted about removing my 1982 alternator last week.

The problem was, the power steering pump, air conditioner brackets
cover the alternator.

Here is how I did it.

You have to remove from the bottom.

First..remove screw holding metal power steering tube from the bottom
frame of the car in front.

Take out the bottom bolt of alternator holding it to bracket and top
adjusting bolt.

Lift out and turn around so you can see the connection.

Use a small screwdriver to unsnap the holding connector.
Take off the small bolt holding the other connector.

With the alternator front facing 'up', slide through the bottom,
moving the metal hose of the power terring pump you unscrewed. (You
have just enough room to clear the alternator from the frame.
It falls out.

Put back in reverse.

Hope this helps.
