Early vs late core supports?

[CopperBronco]

Can anyone tell me why my core support has these 1inch metal tabs that move back into the engine bay? Are these for non V8 engines? Mine has a V8 in it… but core support looks unorthodox with these tabs compared to new ones online? I’m going to be installing a new radiator and shroud, and pretty sure I need to cut these off of core support as I install stock radiator brackets, but wanted to ask here before I cut off anything and do something stupid.

Looks like you have a 6 cylinder core support to me. And I can't tell for certain but it looks like you have a Mustang V8 radiator (or something similar).

So I need to cut those tabs off, right? As V8 stick radiator brackets attach to face of core support. And it did have a 6 cylinder in it originally.

Yes, I think you should cut those off.

Would you cut the radiator hole larger as well?

Considering that they don't make reproduction 6-cyl core supports, I question if the better move would be to preserve it and install a new aftermarket one. There's likely not a huge demand for used 6-cyl core supports, but to the guy looking, it would be worth something.
