I picked up a 4 core radiator/transmission cooler for my 77 and i was wondering what one of the inlet/outlet holes is for. Sorry i don't have pictures but it is the 4th one from the bottom on the passenger side. Obviously there is one for the lower radiator hose, hot trans line, cool trans line, and then what? The radiator i pulled out just had this hole plugged off 
thanks guys
