Call ! 800 LAWN BOY and they can look up parts for your tiller, montgomery wards tillers were made by Gilson. I took the numbers and crossed them on the internet to easy to find numbers; such as the two belts on my gil 39032 d and bought them as the local hardware store. Lawn Boy will sell them to you as well.
