I wish I would of used the 54 235 in my 37 as it will fit with no modifications,it has the same style of waterpump as the 216. You can use the original style fan,the 55-62 motors use a longer waterpump. Shortened pumps are available but put the fan lower than where it should be if you can use it at all,I had to use a electric in my 37. The 54 motor is the perfect one for the pre 47s.
