Excuse me but what is "1967 B body rear end with Dr. Diff's offset hanger kit."??
The rear end from Mopar's 1966-1967 and 1968-1969 B body cars are narrower than your Challenger.
You can easily install a B body rear end in your (E body) Challenger by using Dr. Diff's offset leaf spring hanger kit.
The narrower B body rear end installed will allow you to fit wider rims and bigger tires under the rear of your Challenger without cutting or doing major modifications.
Do some searching here and on the internet for Dr. Diff, offset spring hangers, B body rear end, etc.
