There are 3 different radiators that will fit '38-'39 pickup. One is for the 60 HP engine and is marked 82C on the top tank. The most common one is marked 81C and is for the 85 HP engine. The one with the extra thick core marked 81T on the top tank is for a big truck but it will fit a pickup, and that's what I have on my truck. All have the bracket that the radiator support rods attach to. These rods are of critical importance. You will never get your hood to fit and latch right until these rods are correctly adjusted.
