Where to hook up beehive coolant line?
 

I am in the process of putting a 12a from an 83 Rx-7 into a VW beetle, I want to keep the beehive cooler for now and I need to know where to hook up the upper coolant hose from the beehive? I'm not useing the Rx Radiator, I know I'll have to fab up the place where it will plumb into the coolant system, where is the best place to plumb it into?
