Can I fit a 345/50-14 tire on a stock 71 duster?

I put N-50s on my 74 DartSport back in 1979ish....15 inch Cragars, and Gabriel Hi-Jackers airshocks(I was young). They were not in the wells, but rather under the car;sorta,mostly. Those same tires,with different wheels, fit on my 69 Barracuda, with the same result.

I know it is possible to install 325/50-15DRs into stock 68Barracuda tubs, howbeit,not with out supporting works; including a narrowed rear and springs moved in 3/4",and custom bs wheels. IIRC my 325s on 10 inch rims were somewhere between 13.2 to 13.5 section or 335 to 343mm
