I was playing my SEGA Lost World when the white link that holds the plunger to the flipper assembly broke. I purchased a new flipper assembly (https://www.marcospecialties.com/pinball-parts/515-7203-00) and while I was attempting to install it, the entire screw broke in half leaving the hex bolt permenantly stuck on it. I cannot find another hex nut like it. A worker at Lowe's told me it was a 10-32 hex nut, but when I purchased some, the hex nut was nowhere near as thick as the original meaning it can't keep the flipper in place. Any help is greatly appriciated!
