On second thought, knowing several '40 owners who have gone the original or later unit path, it seems to me installing a correct 1940 unit is probably easier if you are going the DIY path. Wiring harness is available per original, as are all other original parts. Why mess with original?

And Tom, the easiest way to tell is to look at the input shaft tip - pilot bearing diameter for the Custom 8 is about 3/4", whereas the 110/120 unit is about 1/2".
