Hey everybody. Im wondering what the differences are between an A/C core support and a non A/C support. Im assuming its just mounting holes for the condenser. Is it possible/easy/feasible to use a non A/C core support on an A/C car?

Oh, its for a 66 SS.

I converted my 66 from non AC to factory AC. No new holes to drill so I think AC and nonAC core supports are the same.

Yes, the core supports are the same for AC and non AC cars.
