I have the Summit direct fit radiator. Very nicely built unit by Northern Radiator.
As far as fitment: even with trimming the upper mounts it didn't hold the radiator down quite right. Perhaps it is because I am re-using the 6 cylinder radiator hold-down?
To get it to work, I just took the rubber mounts out and used two 1/8" thick strips of rubber instead. Works just fine that way.
