I don't have any spare ones but I did buy a set of new old stock ones from Messics last year.
If you go to the Messics/New Holland site, got to the Parts search box (2nd one down on the left) When searching a Ford/Jacobsen part number always put JAC ahead of the part number, also don't use a space between the JAC and the number. It will look like this JAC343258
that is also the part number of the Knob (bolt for hood), they list it as $14.25 each with 0 in stock, I would call them for help, I did and the woman was very friendly and Helpful!!
People usually removed them as they made it a pain when you wanted to fuel up, you have to unscrew both of them every time, that is why they changed it to a latching type hood.
Good luck I hope you find what you need
