Sorry, don't remember for sure, and the car now belongs to someone else. I believe the lower bracket was bolted to a motor mount bolt. It was a pain to bolt in, but once there it worked well. I remember colorful words and an end wrench. It would have been pretty simple because the whole process was done in a day. The belt runs off the water pump pulley and only runs the alt. Those are the only pictures I have. Sorry, Gene
