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.

You could take that to a GOOD radiator shop and get them to relocate those brackets until the radiator was touching the radiator support. That would give you what appears to be about one full inch of extra space. Course there's extra cost there, but IMO would be well worth it. You could take the measurement before you removed it and have them move the brackets that amount.
