BB - I know I have some, but things are so chaotic with my stuff, post move, I'm not sure where and when I can put my hands on one. They are hefty compared to typical 3/16-18 replacements. I plan to rearrange my two temporary sheds when I have a couple dry days - so if you're not desperate (it's taken me over a week to push this thread to the forum), I'll see if I can dig one up for you.
