‘71 Demon at Mecum $70K lower estimate

Looks like the 68-69 Chargers are replacing E body's as far as $$ goes.
Honestly I never noticed the difference in the wheel openings until I read it somewhere. Now I see it every time I look at one. Dusters and Demons have to be one of the best looking "budget" cars ever made.

What is the deal with charger wheel openings? I'm curious because when I was restoring my Demon I spent a few days researching front fenders because the wheel lip was different than the rear wheel openings. The duster rear body simply got the dart front clip bolted on. It looks odd to me now that I am aware of it.
