Hey gang...
I have a friend that has expanded his factory 3-core radiator in his v-code '71 Challenger R/T to a 4-core. Since the core thickness is the same as the thickness of the upper tank, he needs to find a fan clutch which will work with this modification. Anyone out there running a 4-core with the factory upper 26" tank while at the same time using their factory shroud and fan.

Thanks..
Troy
