I called General's corporate HQ in Canada and spoke to JD. He did not know if there would be a retrofit available but he too was going to check to see if that is something that might be availble. He is supposed to call me back as well and I will also post a follow-up. I am a happy owner of a 350 that is a few years old and it would be sweet if this option was available. Jim's post makes a lot of sense and I am not sure if it can be done on the current saw but we will hopefully find out soon. I always use the splitter for through cuts and an Excaliber overhead guard -- I tweeked my splitter so that it is easy to take on an off but it should would be nice to leave it on all the time and not have to worry about it.
Thanks!
