another will this fit question!!!

Hey everybody....I know this is old hat and much talked about, I just cant find my answer tonight. Yes or no, will a 17x10.5 mustang replica wheel with 27mm offset fit in the rear tub of a 71 Duster? Dont mind the differential issue, I have no rearend as of yet and will be having my 9" modified to fit this wheel. So once again will the wheel and a 275/40 17 fit within this wheeltub? thanks guys! Ps I have an ebay purchase waiting on this answer!
