72 hood fit issue (help needed)
I have been dry fitting my bumpers, hood, wiper door etc as I am preparing to finish the necessary body work to prime etc.
When I fit my hood, the tip of the hood is about 1/8" lower than the nose of the car. the sides of the hood are even with the front clip, and even the front corners are flush with the clip.
What could be causing the hood to be below the nose? I could understand if the entire hood front was below the body, but its not. it starts flush on each side and as it goes toward the center it drops.
Thanks in advance

It could be a several things and I’d check them first then look at a way to fix the issue.
Even though there is very little play in the inner fender to core support bolts, you might try loosening them and see if you can move the nose downward a bit.
The front cross-member is also something that can be shimmed, you may try adding a shim to it to lower the core support if that makes sense..
If the nose is 1/8” below you could correct this by shimming the hood up in the nose and lowering it in the back a tiny bit.

Hi ef,
Is the rod that runs from the bottom center of the core support to the center of the front surround support in place?
Shimming, loosening /tightening, it, MIGHT affect the height of the middle of the surround.
Maybe?!
Regards,
Alan

Great advice by Alan, that rod is where we got ours aligned. The hood needs to be latched, or at least all the way down on the back side though. Then loosen the support rod, and the nose will go up or down just enough to line it up with the hood.

Do you have the radiator support in place? Loosen the bottom two bolts and moving the bottom forward or backward will raise and lower the nose. You may need to shim it some to get the radiator shroud to align.

I was wondering how moving the support would change the nose position.
Actually even with the rod in place it seems odd that it would bring the nose down any. there isnt much play at all (if any) for the radiator support to move back or forward at the bottom, the inner fender holes were not oversized.

Usually the nose droops & the rod is used to push it back up

The best way I can explain the geometry is by taking your cell phone lay it on a table. Lift one end of the phone up holding it between your figure and thumb from the sides to simulate the angle of the radiator. Now push the bottom of the phone with your other finger. Note how it effects the top of the phone where your figures are holding it.
