I Cannot stress enough the pain in the *** it is to time a passenger side input. Damn near put the piston stop in and made a pointer 180* out. Not to mention the 440 source pass side inlet had a heater hose input that must have been made on bring your blind daughter to work day. There was a post earlier from @brian6pac with a cross rad hose. I would use that with a driver side housing any day before I did pass side again. Fwiw this is on 400 Dakota with a rad I had recored,Tanks expanded, copper and brass high efficiency.
