1940 Starters -- Information needed.
Can someone knowledgeable in 1940 starters please answer a question?
I need to replace my barely-working 1937 starter (MAB-4075), and have been offered a 1940 eight-cyl. starter (MAB-4103) by a friend, which I'd like to use. The price is right. [NOTE: I incorrectly called this out as a 4003, earlier.]
The 4103 seems to be a perfect fit, and most of these pre-War starters are interchangeable. (Right now I have a borrowed 1941-7 #MAB-4100 in the car, for instance, and it works perfectly.) Yet according to the 1950 interchange manual, the 4003 won't interchange with any other year of Hudson.
Does anyone know why?
I am reluctant to just bolt it into my car to find if it works, because it it's not right, maybe I'll damage something!
(Also: it is missing a solenoid. That too is supposedly a one-year-only, and I'm wondering why I can't just use the solenoid off my '37?)
I will be grateful for any advice. I'd really like to use the 1940 starter I've been given. Maybe someone with a Hollander interchange manual can discover that the 1940 does interchange after all!
