Plans noted AN3 hardware. Avipro (QB kit) has a 1/4" threaded rod. For the clevis it requires a AN4 bolt. Drilled & Reamed fueslage mount to 1/4". Horizonal Stabilizer Struts have an excellent it. NOTE space that requires shims or washers to prevent crushing the clevis fitting.
Note the 'mascot' keeping watch. My son bought him some years back at Yellow stone and he has been riding with us in the Land Cruiser since for camping trips... the FJ40 was sold a few years back to off the quickbuild kit price, so he has been sitting in the Bearhark Fuselage ever since.
