Champion radiators

In my search for a radiator I have found two different champion radiators one is a 22" and the other is a 26" both say abody 70-75 and both say v8. Which one should I get ? Is bigger better? Will the 26" fit in my 75 dart without alot of cutting and modifying? Thanks
I've never had any issues with Champion radiators. I've used 3 of them so far. 22" or 26", both have worked great for me. I put a E-body in my '76 Duster, had to modify just a little. I put the one made for the Duster in my '74, and fit perfectly no mods. Both cool fine.
