Hello, i'm so sorry - it's more complex of an estimate than the Estimator tool can handle. You'll want to contact a local shop near you to get this quote -- or a few to get competitive quotes. Note that you may want to have this evaluated also - in case you don't need all that work! Use this link to find a shop near you: www.repairpal.com/repair-shops
