WTB: 70 Duster parts car with 8 3/4 rear end

My dad is attempting to restore his 70 Duster and is looking for a parts car. He is the original owner and is hoping to have it rebuilt before he..... well he just wants it done. He needs a few odds and ends but really needs the 8 3/4 rear end and a grill. Preferrably within a day's drive of the Detroit area. Any info would be appreciated. Thanks!

I have a B and an E housing I'm having cut down, and using stock axles. He would probably spend less doing that then buying a complete A 8 3/4
