There are two fuselage era radios on ebay at the moment in case anyone is interested. One of them is: http://cgi.ebay.com/ebaymotors/aw-cgi/ebayISAPI.dll?ViewItem&item=1806560949&r=0&t=0 It's the 71-73 round knob type AM/FM stereo with the cassette plug and, judging by the black inserts on the knobs, it came out of a Chrysler. But it'll work in your 71-73. The other is: http://cgi.ebay.com/ebaymotors/aw-cgi/ebayISAPI.dll?ViewItem&item=1806870768&r=0&t=0 This is a thumbwheel-type AM/FM/8-track unit and it's a little rougher. Probably a 1970 unit but possibly 1969.
