first got to www.simplicitymfg.com and plug in your mfg# which should be 1690204. Pull up your manual and figure out what the part numbers are and what they are called. then go to eBay and start looking through the parts. In the meantime you might call Brenda at Sandy Lake Implement Co www.sandylakeimp.com and give her the part numbers and see what they would cost new. If the prices are not too stiff you may want to buy from her but at least you will know what they cost new and will not overpay on Ebay. You will love working with Brenda, she is an avid collector and restorer of Simplicity and Allis garden tractors.
