I kept both the starter and alternator from my 7.3 and had rebuilt locally. Got lucky and picked up a new motorcraft starter for free, rebuilt original is still on the shelf. Bought the lifetime alternator from Napa, bet I've warranted it 8 times. Throw the rebuilt original on until I get time to change it back out. They must have finally stepped up the quality tho, haven't had to change one in couple years.
