Here is another option for you.
Do you still have the old belt?
If so your local auto parts dealer may be able to help you.
I got mine at CarQuest
If you feel comfortable with cross index catalog check with Gates Rubbers
site http://www.gates.com.
You may have replaced the belt before and know how to do it. If not
check with http://www.newwoodworker.com/JWL1236tips.html
Now I only use belts made in the US/Canada. The OEM belt (Taiwan/China) do
not last long.

Is it a V-belt? If so, use link belt.
