trying to install a radiator from a 68 roadrunner in my 69 but it's too big. did the factory install 22" radiators in the roadrunner?

 

Yes,22 and 26

 

its no big deal ,if you dont car eot drill holes in your rad support, put hte 26 " rad in place then move it so your 2' over the sides on ither side then line up the old holes verticvally w/ the strap holes on the rad, then mark the spots on the support past the old holes and drill the new ones. no fuss,no muss. ive done it to several cars, especially when the small block came out and the 440 went in.
