ZR-1 Net Registry Forums - View Single Post - DeWitts "Direct Fit" seems too thick to fit- what am I missing?

I spoke to DeWitts and they are a stand up organization and will refund my money.

So, I'm going to have to "ride dirty" and go with a plan B radiator.

Any recommendation-- and part number-- of a radiator that fits/works? I'm calling the part houses and get different stories where some say a ZR1 radiator is different than other c4s and others say they are the same.

My current one I pulled out is (approximately) 23 1/2w x 17 1/2h x 1 5/16 core thickness hand I had no problem with cooling. No part numbers on the radiator to cross reference and the old invoice number show a generic C4 radiator.

The one that keeps coming up is a ACDelco 20681. Any thoughts?
