72 Dart - slow revival

if you're going to order new axles why not shorten the casing to 'a' body width now. another of those things to do now rather than regret it later?
Thanks, if my calculations are correct the difference is only 5/8” or 5/16” per side so I don’t think it’s worth the trouble. Could go narrower just for the sake of bigger tires but probably overkill for this car.
