If you have all Chevrolet parts, you need to recheck the gaps at all four cab mounts. Make sure that you measured from the correct points. I little bit off on those areas creates a huge error at the radiator support.
I checked again and those measurements are quite near what they should be. The hood is stopped closing when the bottoms of the rear curve of the hood hits the cowl. I previously said that all parts were original GM, all except the lower cowl. Original was replaced with aftermarket due to rust. I'm thinking maybe the curve in the cowl for the hood is off. What is the next adjustment?
