1974 Barracuda measurements needed

Can anyone measure the distance from the firewall to the upper radiator support so I can reference against mine? I started test fitting the new body parts and I have a huge gap between the hood and the new header panel. The fenders fit as they should and line up with the hood well. The front valance fits properly as well. I repaired the lower radiator support and I fear it may have moved because the new header panel is the same as the old one. Any help is appreciated.
