Got a 140 amp for a '94 Pontiac Trans Sport, doesn't bolt right up...... What should I do? 1. Break out the welder and grinder and 1.5" square tubing and attempt to build an extension onto my current bracket? 2. See if I can't find a custom bracket aftermarket? 3. Take it back and see if the '86 Buick Park Avenue 120 amp alternator bolts right up? Here's how close the Pontiac alt. is......My stock bracket needs to extend approximately 2" further out to be able bolt up the top half of the alternator. This is as close as it can get without the alt. fan rubbing the bracket. One last thing....The pulley on the Pontiac is 5 groove, I have 4 groove. Swap pulleys or can a 4 groove belt properly run the alternator.
