2 oblong holes on radiator core support? WTF are they?

Not an AC car ever. My first thought were hood pins too, but think it has to do something with its past as a drag car. Bare bones car with vinyl floors, radio delete... just motor, trans and shell.. The holes are oblong from some type of lateral force that over "time" opened the holes without any distortion to the surrounding area. I thought maybe some type of bracing that would stiffen the frame somehow... Who knows - I'm going to fix em and make it right. Thanks everyone.
