Yup. Just went through this with my '86 which even though it has the towing package and auto trans, only has the two-core radiator with the offset cap and recovery tank since it has a clutch fan. My '83 had the non-clutch fan & towing package and had the same 3-core radiator that you have. Wasted $50 having my extra one repaired last year for my project Jeep, so I yanked the clutch fan off the 4.0 and installed a dual electric fan setup instead.
