He explained to me that when parts are shown on the EPC online parts catalog diagrams but the parts list states that the part is not needed, or not for the model in question it is because the filters are turned on and are telling the program to not show parts that are not relevant to the model you looked up. The diagram may be used for a number of different submodels so some parts are not necessary for the specific model. In this case, I needed the part that was shown to work with the alternator but was not needed for that model. I could see the picture of the part in the diagram but I could not see any part number information or availability notes. SO...Steveb taught me that if you go up to the filter icon button at the top left of the screen and bring up the filters screen you can turn off all the filters and when you return to the parts screen the part information showing the part number and other info will be shown. It was exactly what I needed to get a part number for the alternator rear cover that was shown but was filtered out.

I am going to try to order the cover and have found a few other cover part numbers from the search that I will check availability on that might work. I still have not found a metal heat shield part number for the AL66X or AL165X Bosch alternator. Any help there would be appreciated.
