1973 Dart Swinger cooling

Yup 904. There are 4 bolts that hold it to the rad. In the photo you can see the top one clearly.

Thanks so is there just clips on the rad that the bolts screw into? Also seen a car like yours think it was a 1975 guy ordered it New with 318 and a 3 speed standard with overdrive never seen one before with a standard.
