I think on your wagon, since you have been presented several unattractive options, instead, use a '68 to '72 Chevelle 12 bolt. It's about two inches or so wider, that can be compensated for by rim selection, and if you want to put good axles in it and a C clip eliminator kit, the flange width can be adjusted then by whoever does your housing work. What is a rare item, but might be found also, is a '72 Chevelle 8.5 inch 10 bolt. I'm not too sure what those came in, but don't confuse it with the 73-77 unit. It won't be easy to find,however. At least the 68-72 12 bolt will be a bolt in under that car.Good luck on what looks like a fun project!
