I think you scored great! Those rear wheels will be tough in the turquoise...I've been down that road and they're bigger than the front...so you need the real rear wheels.
Rather than wait an eternity for that filter housing....I'd make some close-ups of the housing from the literature(or from a willing member)and have it fabricated by a metalsmith(I assume it's metal and not plastic? If it's plastic, 3D printing). Considering how much these go for restored, I think you'd be money ahead.
