Original factory part, for V8 w/ A/C air-conditioning or K-code 289 Special use. Stamped steel one-piece type, production black paint. Early version has an 18-1/2” diameter center hole rim all around, is reasonably straight w/ a couple corner cracks & extra holes, performs well. From a ‘66 w/ C4ZE-M2 radiator it suits ’65 models too, however the service part and ’67 up are different. It’s an OEM Ford item w/ correct form & fit, for an air-conditioned or high-performance Shelby GT350 / 2+2 fastback / GT coupe / convertible, why go repro.
