Barnfind - Being that you're in CT, this is maybe also too far out to be worth your while, but I found this
Saginaw 3 speed w/OD in Fairmont, MN. As noted in the original ad, it is missing the solenoid.
Asking price is decent at just $200, but a trip half way across the country may be more of a road trip than you want to put into it.
