they were of course proven by military use in w/w 2 with the kubel and schwimmer, long before we got to lower them with swayaways....
The reason for asking is some debate as to how good the generic no-name Puma beams are. The original beam has a depression in the beam itself, gripping into the centre-piece. The Pumas does not, as far as I have seen, this. Only thing then holding this is the shear force from toothed-plate and if that fails the bolt itself shearing against the beam.

Would be nice to see how you made the preload bushes and installation.
