My Grumman TR2 had a flat fiberglas laminate plank bolted to a cast
aluminum fitting on the spar. It seemed to work pretty good. The nose
gear leg was bolted to a torsion bar which ran across the front,
inside the firewall, that also worked pretty good.

My KR-2 fixed gear has the same setup with the fiberglass plank and aluminum
fitting on the spar.
