This may be obvious, but this isn't an official limitation. When you see the maximum DEMONSTRATED crosswind component listed in POH's for certified airplanes, you're simply seeing whatever the highest crosswind component was that they encountered during their flight test. It is not a limit for the airplane.
If you're willing to land the plane sideways on the runway, then the amount of sideload that could be handled by the gear is probably going to vary quite a bit across installations. I suspect the only consistent number would be a figure for a slip with the nose straight, and that should be relatively consistent across small tail LNC2's, then something else for large tail LNC2's.
