Radiators in an A-body?

you don't need to cut the support, to install a 26" one, your just not going to get all the potential airflow though it. i used it because i already had it. it's sure not going to cool worse than the 22".

That's why you would cut it. For the airflow. He is looking at potentially using a 26" because of wanting additional cooling. What would be the point of that if you didnt open up the support to take advantage of it. In your case it was just a matter of you had it, so you used it.
