It depends on year / make / model . The 1970 B body AM 8-Track for example is a thumbwheel (same radio as the 69 B body AM 8-track ). All 68-70 B bodies used an AM 8-track thumbwheel . All
E body AM 8tracks are thumbwheel . C body AM 8-tracks are thumbwheels starting in 67 , but some latter on were knob style .
I would assume you are asking about a 70 B body .
In that case, yes, exact same radio as '69 B body. The 68 is slightly diffrent , diffrent vendor, diffrent dial face lettering, (Dodge or Plymouth as oppossed to Chrysler lettering for the 69-70)otherwise identical to the untrained eye , but lots diffrent on the inside.
