I am currently rebuilding my 1964 Johnson 9.5 and the exhaust housing is cracked and I need new (used) one. The exhaust housing part number for my motor is 380043 (same for the 1965 as well). It changes in 1966 to 381280. Does anyone know the difference (if there is one) between the 2 different part numbers. I have found an exhaust housing for the 1966 on ebay, but want to make sure it will fit before I purchase it.
