You can get an alternator that looks like a generator from classic Jag shops like Moss Motors, if that really bothers you. I would just stop dickking with it, if it were mine.
I grew up in Vallejo and 73 'Old'-now, I don'r remember this Hod Rod there, but being a huge carguy all my life I really enjoyed readin about it's history. I went to the Oakland Roadster Show many times before it moved, so I could have seen it there and didn't realize how Cool then from where it came and to read about it now is Cool. Thanks
