So I took a couple of pictures of my current set up as there is some discussion about it above. I've not measured but it looks like I've got about 3/4 to 1 inch space between the fan and radiator. It does have the fan sitting at the bottom half of the radiator vs the top, not sure how much if any that changes anything?
On another note, my throttle rod appears to have nothing to hook to as the drivers side of the carburetor does have anything for the rod to hook on to.
