Old style crager wheels and tires fir my duster. Opinion needed

I seriously doubt a 15x10 with 4" backspace will fit anything but a pickup truck, without lifting the *** end of the car to the moon.
At some point somebody put longer shackles on my duster.The back end sets pretty high. He said his fit his stock duster 8 1/4 rear but rubbed the spring about 1"
