Answer
Hello Mike,
 It sounds like you may have a hard time getting parts for your vintage Bombardier-Ski-Doo, since for the most part, parts aren't being made for them any more. A couple of websites that might have a few parts is: www.alssnowmo.com, www.denniskirk.com, and www.mfgsupply.com. As a last resort, and if the cylinder head's bore isn't dmaged, you may be able to take it to a snowmobile repair shop to have it welded or repaired. As far as I know the Bombardier-Ski-Doo Alpine was the only sled made in 1964 with twin tracks so I'm guessing that's the sled you have. Good luck with the sled! Mr.W
