Tom, there is 1 1/8 " between the radiator and the light bar. I think the problem is the repro headlights. The 'ball' part of the ball and socket does not appear to be as large as the originals. I tried putting dished washers in the socket, but that does not change the angle of the socket. I instead cut a dished washer in half and placed it in the back of the socket. I am now able to aim the headlights. Not perfect, but it works.
Regards, John
