Cold Case 26in Rad fitment

This is why I created this post. After reading different radiator installations most said that the Hayden clutch would work and it will not. Im going to wait and see what go-fish finds out with the Rad he ordered. But to all trying to install a Cold case MOP750A in a 73+ abody will probably have to use a flex fan or electric fans.

I will be trying this radiator 26" Small Block Mopar Radiator in a 1973 340 4 speed Duster. It is 1-1/4" wider than the Cold Case 26" rad. The CC is 24.3" and the Engineered Cooling Products is 25.5" wide. The ECP is 1/8' taller and wider on the overall W x H.
Currently I only have a non-clutch fan and will be ordering a Hayden 2947 today. Anybody have a link to a fan to use?
Radiator should be here next week. $316 - shipped. They have flat rate shipping. The price of the radiator is around $277 + tax. My cc was charged by Entropy Radiators in Florida. I looked at Entropy Radiators website and they don't have any item such as this. They make $1000 + radiators. Maybe ECP is their 'budget" brand?
