Andy, I hope all is well.
I read about your situation and can not keep from wanting to help. (sorry I didn't see this earlier)
Everything I have is from a 440.
I have a couple carbs, probably needing a rebuild but are complete. What size are you looking for?
I also have a distributor.
I have a balancer if it's for a internally balanced crank?
Please let me know.
I want to make what ever difference I can to help out.
Thank you for being an inspiration to myself and others.
Tom
