I have a 71 Challenger and can get a nice deal on a AMD one piece floor pan that is for a 70. AMD has different part # for the 70 and 71-74. I have looked at other brands they have the same part # for 70-74. Is there a difference? If there is what would the difference be? Thanks for any help!

However, that change didn’t occur until sometime in the 1971 production year, so depending on your build date, a 1970 trunk pan might be correct for your car. My ‘71 Challenger with original sheet metal was built in late October and has the 1970 style trunk pan. I don’t know when the changeover to the new style floor took place but at least for cars built early in the run a 1970 pan is what is needed.
