Not sure Marty but believe you have the wrong bolts with captured washer in the hinge to fender location. Or at least they look too large..... Our AIM and also the 69 I believe call out the 9301 bolt which has a 1" captured washer. In that hinge to fender location the assembly line used the same type bolt but it only had a 3/4" captured washer and only used the 9301 in the hinge to hood location. I just went through all of this on our 68 and members were helping me understand. To date I'm not even sure what the GM part # would be for it.

Chick - I can't remember if we covered that bolt over at the fastener threads. Can you do me a favor and post a pic of it if you have one handy? At any rate, rotating the hinge like Scott mentioned did a world of good. Lets see if it holds once I install the new seal.

Another question; what should the reveal be all the way around...cowl area, fenders and front?

Thanks

I looked right through that Chick. Those bolts are wrong and will limit adjustment. Put the correct bolts in and you can bury the hood more. I'd just keep the gaps consistent. If you can't you have to start adjusting tin. What do you have now, 3/16"?

Well...3/16" east & west & way off north & south. Too tight on the cowl end. My guess would be loosen the hood to hinge bolts & slide it north, correct?

Forget about the cowl. The hood gets adjusted to the fenders and header first. Then adjust the cowl to the hood. If the side and header gaps are not consistent, the nose is racked and has to go left or right.

The nose is not racked. The hood is true to both fenders. My problem is a crater at header, 5/16". So, do I make this up by loosening the hinge to hood bolts and easing it forward?

That's good. Just bump the hood forward and you're golden. Then move the cowl panel forward if you have to.

No we did not Marty and I will take care of that in the near future. A friend is sending me two different origiinal bolt heads used in that hinge to fender locatiion.  AMK has screws with the captured 3/4" washer that could be used but they are pointed and longer which is not seen when installed anyway.

I'm in no hurry because the hood looks better now than it ever has thanks to the ABC's of hood installation via Scott. Hats off to him. I don't think there are too many guys out there who can guide someone through this complicated process without seeing it in person and nail it. Yup...I'd have to say he's done it a time or two.

Anyway, thanks to you for spotting the wrong fasteners! Once I have the correct ones in place I shouldn't ever have to mess with it again. Please post pics of the originals once you have them.

Oh yea, Scott has helped many of us at sometime or another. Know he's helped me!
Again, will do on the hinge bolts.
