I agree with Jim. I had a new radiator made and installed at CG&J in Gadsden AL for my Windsor back in 2015. The very first thing I noticed was my transmission temps were 10F higher than with the old radiator. Plus, the new radiator started to "seep" at the top about 3 years later. One bottle of Irontite solved that issue.
I, also, no longer recommend CG&J for any radiator work.
