S21zpr locate a throttle cable to purchase

[Mrfixitmower]

Hi I have a Lawn Boy S21zpr the throttle cable broke I need to find a new one and I'm having trouble locating one. Any ideas or thoughts. Casing is about 48 in and the wire is about 50 to 52 in it's not a big Z connector on the ends but it does have Z on both ends.
