Cold Case 26in Rad fitment

I received my cold case 26 in rad yesterday, and have began the installation in my 73 valiant.
It looks like I will have to modify it with some holes to mount it to the car as the current holes are not even close to lining up. Has anyone else installed on in a 73+ A-body that can provide pics on bolt modification? Another thing I wanted to see if there is a way to use a stock radiator shroud? If not does anyone have a recommendation on a direct fit shroud?

I have also attached photos showing the space between the Radiator water pump pully. I ordered a Haden low profile clutch to run with my stock a/c car 7 blade fan.
