What year? If you have a 2.0 I believe only the '74 Pinto had a plate to use the smaller 2.0 radiator in the larger opening. So if your Pinto is a '71-'73 you will likely have to increase the cradle opening for a larger radiator. See the last picture, the cradle was widened about 3"-4" and the metal overlapped to provide strength. With the 2.3 Turbo (no mechanical fan) in a '71-'73 car the clearance in very small (see middle picture). An FYI, the '71-'73 has a 17"radiator and the 2.3 cars had a 20" radiator (See first picture).
