moorerp:
sorry, I wasn't online yesterday, so I did not see your question. The hitch will fit an 81, because they are the same as an 83 under the rear where it goes.(will even fit my 79) If you go to etrailer.com, and in the search on the upper rt side of the site, you can type in the 247223 and it will give you the info, and a nice picture of the hitch. Bob
