In your case this is the way the resonator looks like. No stainless steel tip with rounded ends. Just simple a straight cut on it. From the date Chrysler suspended the old style resonator they on some assembly lines used the new ones but also continued to use the old style til they were gone! My is date coded 11 - 64 meaning November 1964. My car was assembled January 27, 1965.
