Fitting a 26 inch radiator?

Hi all,

I just posted a "wanted as" here for a '75-76 Dart Sport front clip, and it just occurred to me - I have a 360 and will eventually be putting the AC back in, so I'll probably need the 26 inch radiator. If I get the front clip from a slant 6 donor, will I be able to easily modify the radiator support to fit a 26 instead of a 22 inch radiator?

Thanks.
