do i need to drill new mounting holes for a V8 radiator in a /6 car?

went to install the radiator from the 76 dart into the 67 car last night and it fits perfectly - except all the mounting holes are off. obv the smaller radiator of the /6 has a different hole setup. so at the risk of asking an idiotic question, i assume i need to drill 6 holes to mount the V8 radiator.

does it make sense to attach the shroud to the radiator to make sure of fan clearance and then mark/drill the holes?

sorry for dumb questions ..
