Ah CRAP. I may as well post my own correction. The 124 300 D's were all 6 holer 60 series Diesels. I don't know why I always think they are 617 motor 5 holers. There was a 4 cylinder Diesel made, a 200D for other markets, that's the 601 motor, also a 5 cylinder 602 motor, which was the 250D, also of course for countries other than "US"....Gilly
