I went out to the car and took the fan clutch off the car. I was then able to get a exact measurement from the front of the pulley to the radiator. 3-1/8". The Jag clutch is 2.67" that only leaves me with .455" between that clutch and the radiator. I still fear that, that is still to little of room.
I know of another guy that has this same radiator on here so Im going to ask him to get me a measurement from the brackets to the front and back of the radiator. I just wonder if mine was welded in the wrong spot, (to far back)
