B body A833 shifter placement

I am gna fabricate a mount for the B tranny if I don't find an A trade by the weekend. Has anyone done this already? Lookin to swap a B-body A-833 with shifter for an A body style to hook up to a 440 in the Granny Duster. I have the BB bellhousing. I'm hoping to do this in Canada (ideally in Manitoba) because of the frieght.
