I JUST GOT A 1977 TAHITI 19 FT JET AND I NEED SOME HELP. CAN ANYONE TELL ME WHERE I CAN GET NEW FRONT SEATS AND A BENCH REAR SEAT FOR THIS BOAT? IT NOW HAS THE LITTLE SIDE REAR SEATS BUT I'VE SEEN OTHERS WITH A BENCH. MY OTHER QUESTION IS CAN ANYONE TELL ME IF I CAN CONVERT THE EXHAUST FROM AN OVER THE TOP TO ONE THAT COMES OUT THROUGH THE BACK? IF SO WHERE CAN I GET ONE????
