1962 3000 Hood/Bonnet Grille

i am trying to get my surround and grill in the bonnet fitting properly. if i just mount the surround, it fits fine. when i add the grill and take up the nuts it twists my surround. Not much but i have some scratches on the side of the scoop that i want the surround to cover... and it does if it fits right.

Looked at the Moss breakdown today and it shows a packing washer that goes between the grill and the surround. (i assume under the hood metal) it does not give a size for the washer. i assume that is my issue with keeping everything fitting properly.

would anyone remember the size of that washer? inside diameter and thickness?

Thanks

Make sure you use a fibre/plastic/stainless washer . Fibre would be my first choice just regular washer size to fit the stud should work .

But how thick is it?
and does it fit in the grill slot or to it?
thanks

The fiber rectangular washer goes onto the stud first, and is above the slotted holes. The inner grill goes in from below, covering the lower raised flange of the bonnet opening. Then attach with flat metal washer, lock washer, and nut. Do not over tighten.

Thanks again.
hate to keep beating a dead horse but I feel like the thickness of that fiber washer is important. Which is why I ask. Maybe it isn’t a big deal and I am over thinking it.
But just want to confirm.
I was thinking of running a nut up in there before pulling up the grill. Would not only give me a spacer but keep from pulling on the surround stud when tightening.
thoughts?

These things are a bit delicate, so it's good to see your cautious approach. I could be wrong, but the main reason for the fiber washer between the chrome surround and the hood/bonnet may be to protect the paint below from chipping or scratching. A nut may be too thick, unless you grind it to a very thin profile first. A small metal washer might serve the same purpose as the fiber washer, except that you run a greater risk of damaging the paint with a metal washer. A small O-ring also likely would work. You seem to understand the importance of not overtightening the nuts, as the studs do separate from the chrome quite easily. If you need to tweak the shape of the chrome surround (they don't always fit great), do the test fitting before installing the nuts.
