Hi there, I recently purchased the cold case chn543 radiator for my 1968, small block, manual nova. I briefly looked to see if anyone made a kit that would work with that kit, but I haven't found one yet. Is there any kits that people are running with those Radiators? I was also wondering what kind of radiator bushings people are using, the 3 row or 4 row style? What kit are you talking about.
