Cost estimate on timing belt and timing belt tensioner on 1995 Ford Mustang

Ford is quoting $282 labor and about $180 for parts (timing belt, tensioner and fuel filter replace). Is this a bit expensive. Thanks

The 1995 (232) 3.8L Mustang has Timing Chain not a timing belt. The older 4 cylinder Mustangs had a timing belt. What is the year and engine in your Mustang?
