Will a 66 b-body 8 3/4 fit without cutting?

MOBodyman is correct, the 67 and earlier b body rears are narrower than the later ones. I have one in my Duster and the cop wheels with 255-60-15 tires fit great. All the charts fail to list the pre 67 axles being narrower than the 68 t0 70. When I can I'll measure mine and post the width. My 8 3/4 is from a 66 Charger.
