I have a housing that is scrap, had water in it for years, seems it'd be a good donor for backing plate flanges. Or if you had a housing that spun a wheel bearing, that'd make it pretty much scrap too.

You can swap gears and carriers around. If the housing is junk just keep the 3.42 gear set complete with carrier and pinion bearing housing.
