Wow. Good question- I'm not too shur. I would try an ol'fashioned hardware store maybe Ace and the two I know of are Harborshops & the other is next to Quaterdeck just off Cordova.
Yoycan often get parts for these through Hime Depot on line - they ship to your store or home. Other option is to get comolete model & serial number and search in line - Amazin and eBay almost always has what you need at discount prices.
