Radiator help needed!!

I had the same issue with the 3 core on my 65 Cuda. I just bought a reduced length fan spacer and that solved the problem. 65'
Awesome. I had no idea that was even an option.!!

Do either of you remember where you purchased a low profile fan spacer? What about the length of the bolts going through the fan. I will need to get shorter bolts as well I assume
