I hope this helps others:
The Bosch AL655N was a great replacement for the OEM alternator on my '72 3.0cs in regards to fitment and alignment. One of the threaded bolt holes had to be drilled out to accept the slightly bigger factory mounting bolt and took less than a minute. The pulley had to be swapped over. We now have 14 volts at idle with AC Condensor Fan, Lights and Wipers on as opposed to 12 volts and the lights going dim. All with the comfort of a new "made in USA" Bosch alternator. We also used this plug for a cleaner install in regards to the D+ battery light wire...
