Which I can do as I have both available. It may be that it crashed hard enough to bend the washers under the screws heads, I haven't pulled either all the way out to check that, but will. If they are bent, we'll have to locate some harder washers. I do know they are a bit thicker than usual but not if they are really good steel. Ought to be at least 4130 I'd think, 4340 would be even better IMO.
