That will help like Kevin said if you take a picture of the front of the engine and the waterpump to determine if you have the older style waterpump.It looks like you have a unique casting number maybe a Canadian thing eh .also include in your picture the plate below the timing gear to see if it has the provisions for the motor mount .I am going to guess that it looks to me that it will bolt in without altering anything .
