hey vin, i just bought a rj 59 today, and I was wondering what you knew about them, and what are the diemntions and pieces I would need for the exaust, someone put a different 1959 or 1960 kolher 4 hp so the correct year but I need exaust and cover, and I know packratsfabracation made a video about, but the tranny is terrible loud and clicks when pushed backwards, but it runs beautifully. just have those few questions, and sorry if that was a lot- thanks, Keaton
