I have been dealing with this problem for months now but still no luck finding a part. If anyone has a 351 h.o or a windsor from 85-86 check and see if you have this bracket that i need. There is a small bracket that bolts to the adjustment bracket to the engine block just below and behind the alternator. If you have a bracket here please send me a picture i have been looking for this part for a long time. Without it my alternator loosens up and throws the belt and then i have to get a new belt before i can drive it again. If anyone has this part please let me know so i dotn have to try and make something work in its place.
