The other problem with this,I am using a motor plate, While it may not matter, it is another 1/4" or so,But I used the stock water pump this way and had no problem, in fact wish I had never seen this new one,lol Stock one worked fine,but the motor went bad, new Moroso kit was $79.00, this was $100.00. Actually a 69 Mustang Blower motor looks the same as Moroso water pump motor and NAPA has for $23.00.
