I put a 261 in my 39.... didnt research enough before hand. I put the water pump that goes to the 62 261. Needless to say its too close to the radiator for a fan. I just ordered the adapter plate to use the earlier style short shaft pump which also raises the fan up to the location it was on my original 216
