Advice asked for widthening rims on a 70 Duster

If you want to find a decent selection of tire sizes, ditch the 14" tires. Pretty much obsolete these days.
Thnx, I found out that much indeed, I have a brandnew set of cragar ss 17/45/235/8" which I temporarely mounted on the car with adapters to convert to the 5 x 4,5 pattern ( they will go on my 69 charger when finished the resto one time) , but due to the adapters the rims are 1" too wide for the Duster, exactly the thickness of the adapters. I want to keep the 14's because of my budget. Converting to 15's would mean new rims and tyres and when not using the adapters I would have to convert the rear axle... Pretty costly, want to avoid that
