Almost everything for the front sheet-metal is 5/16"-18X3/4".
However there are two inner fender to firewall bolts each side that are 3/8".
The hood to hinge are short or you'll dimple the hood sheet-metal.
Also a total of two front fender to radiator support that I think are 3/8".

I had previously found some correct dimension fender bolts from the bolt barn (shown in the pic in silver) However I have since found some from Cllips and Fasteners with a dog point. Also classic parts dot com has them in dog point that "look" correct but I dont have a washer dimension - should be 13/16".

Classic parts - https://www.classicparts.com/1955-66...info/37%2D925/
Bolt Barn - https://www.ebay.com/itm/50-5-16-18x...-/261413110982
Come to think of it I did buy a bolt kit from ebay when I started, but that was just to get it to paint.
