Going from memory here, but when I rebuilt mine, I thought it was a standard square key. You can buy "key stock" at any good hardware store. Bearing houses always have it. If it needs to be reduced in size for a sliding fit, you can rub it on some emery paper set on a flat surface like a table saw. You only need to take a few thousandths off.
