Need a radiator
 

I'm new to this forum so may not have this in the right place but here goes. I have a 2004 Mercury Grand Marquis that has a leaking radiator. I was looking on line and found listings for radiators with 25 3/8 in between tanks and 27 1/2 between tanks. Are these radiators interchangeable? I have the 25 3/8 one now. Will the AC condenser and oil cooler mount up to either one or do I need to stay with the size that I have?

Thanks for any help.
