Hi John; I can get you some measurements if you let me know what you're looking for and the specific hitch. I can tell you the # e54KR you were looking at is designed to fit the 2011 - 2015 Kia Sportage excluding SX models and the 2010 - 2015 Hyundai Tucson so it will not fit your 1984 Toyota Pickup. We do have the # e96KR which is confirmed to fit your truck. view full answer...
