Hello,
Based on your dimensions, our 23-043 seems like a good match but make sure to compare the dimensions on our product page to yours to confirm. Though it's not a requirement, if you want to stick with steel wheels you can purchase the 82-226 81-266 roller and axel kit to switch out the nylon wheel that comes with the 23-043. Take a look and let us know if you have any other questions. Thank you!
