hood hinge lock washer recipe lol

Dont know if this has been posted before because i couldnt find it. I figured out how to get around buying the hood hinge lock washers that go inside the fender. I took a 3/8" washer and a drill bit 1/2" (i beleive) and counter sunk it. By that i mean i didnt drill all the way through it so that one side was 1/2" and the other was 3/8". After i did this i took a socket the size of the washer with an extension and place the washer on the stud and hammer it on. Its a really snug fit and im not worried one bit about it coming off without lots of prying lol could always put a tack weld on for extra measure. Worked perfect and had not trouble getting it on.
