Another champion radiator chapter with pictures

Ok, So I'm getting ready to do my 360 swap into my 68. So is this the correct part number for the newer style water pump and a 68 Barracuda? The e-bay store linked shows it for B and E bodies not A bodies. Is that why you have to modify the lower crossmember? I may be willing to do that as well, just need to know what I'm looking at or if there is a better part number for my app. It's just a mild 360 magnum hybrid and an auto trans. Not sure what fan I'm going to use yet either.
