just check ebay that stuff is on there all the time. or look for a parts saw (been sitting for years will run with a little carb work may need tune up or gas tank cleaned) :jawdrop:
Hey guys, I have seen the spikes you need on ebay. They were not on a parts (junk) saw but were sold as a pair new in the packaging. The way they were advertised is that they fit the 1-10, 10-10 and 610 pro. Hope this helps. By the way I have a 10-10 and it is a great saw.
