Access the starter from the bottom when you have the car jacked up in a safe manner... You can access the wires from under the car and also by removing the Air Cleaner on a diesel. Be sure and disconnect the battery... From under the car you will need to remove two(2) allen bolts that hold the starter in place... use either a 8mm or 10mm allen socket.. Torque will not be to bad.. I usually use a short pipe over the rachet to help.. Some of the starters have a small bracket at the front of the starter but I think they are rare..

If you need a used starter in good condition for a 126 just let me know your location and I will give you a good price.. Jim
