I can't find this Rad (2949015) in the listings but believe it's for a 225. It's been modified to have the outlet on the drivers side for the 360 water pump.
Slant radiator was set up for hose connections offset to the right.
You say the engine is a 360, with pump inlet on the right. So yes you can get away with using this radiator.
What you realy need is a parts store that has the hoses hanging.
When I got my car (67) it had a later square tank slant six radiator.
I have one note scribbled saying the connections were 1.5" diameter and the length needed is about 20"
Anotehr note that I later used upper hose 21202 with 1.75 to 2" cut off from each end. That's probably a Dayco number.
I can not guantee the later square tops put the connections in the exact same location as the bubble top radiators.
