I HAVE A SOLCAT 18 ALL OF THE LINE,BLOCKS AND SHACKLE ARE MISSING. WOULD 2 RONSTAN 29MM FERRULE EYE HEAD AND A HARKEN SHACKLE BOW 5MM WORK? THERE IS A PART ON THE TILLER HANDLE THAT IS MISSING THAT HOLDS THE RUDDERS DOWN WHAT IS THE NAME OF THIS PART? I BELIEVE THAT THIS PART SWIVELS, THAT IF YOU HIT SOMETHING WITH THE RUDDERSIT WILL RELEASE.
