No worries Jeff, couldn´t accept that crap. The seller in the Netherlands didn´t mind and gave me the nice 5.8 hulls instead. Had to pay the shipping though. One of the guys in the 5.8 FB group said he had a pair of inserts. I made the new beam of 2x100mm tubing and the center and inserts of 3x100mm that I slotted 15mm for a tight fit. Then a M8 bolt through the beam end, like the new 5.8, with spacers from top to bottom. Used stainless 40x3mm for the beam strap and M16 for the striker rod.
