Depending on the Age of the saw. You may be able to get it from the Mcculloch company if it's fairly new but I'm not really sure. Some manufactures have online sources that you can download but I could not find mine with Mcculloch but I have not called them to verify if it is or is not available. If it's vintage you will probably just have to watch ebay and they sell for about $8-10 there.
Two sites with good information on chain saws:
(1) The chain saw collectors corner - Complete listings by Manufacturer that describe the specs of each saw and the year manufactured.
(2) Oregon chain saw chain company - They have a wealth of information on bars for your chain saw and the correct chain. It's an easy look up system by just inputing the manufacturer and model. Information for my saw poped up and it is 35 years old. How to maintain the bar and chain is very interesting and a science. It is easy to read and understand with pictures and diagrams.
You can just google for the names above to find them. Maybe this will help someone.
