Hello. I'd like to know if the 1981 244 GL external parts and 1976 244 GL external parts are interchangeable. I'd like to replace cracked rear light plastic covers to start with, and if the parts are interchangeable I might get an engineless 1976 244 GL, which I can get very cheap - though, I haven't seen the Car as yet. I should be grateful if any of owners/mechanics out there would direct me to the right direction. Thank you. m.244GL.au
