Hello all iam restoring a 70mach1 and want to know where the factory hole is in the radiator support for the oil cooler lines go. I have photos is it the first photo or the second.

I've seen some pretty ragged/butchered from the factory, but the way I think they were supposed to do it involved drilling a hole with a hole saw top and bottom of the A/C line knockout in your upper photo, then knocking out the rectangle to end up with a sort of oval or oblong hole. Use the existing holes top and bottom of the knockout as the pilot hole for your hole saw. For the lower line, there was a hole drilled or punched in that sloped section just above the hole you show. Not sure how that one was done. Maybe someone has a good picture to post of an original car that doesn't already have the cooler lines in the way?

 

EDIT: I just remembered, there is great detailed info here:
