I have a 1960 gas 641. The exhaust set up was wrong when I bought it but it worked so I left it with the vertical muffler configuration it had. Now the muffler has a hole in it so I'd like to set things up right with the correct muffler horizontal near the exaust manifold like my service manual shows. I can get the muffler clamps and the straight outlet pipe locally with no problem. I want to order the right muffler and the model specific outlet Pipe support. I always check this site first but have not found these parts here or elswhere. After paying $70.00 for a gas petcock that lasted a day, the New Holland dealer is a last resort.
