Go to this site with your model and serial numbers and you will find all your part numbers. I always recommend buying from a dealership, why? When you buy from them you will get the parts you need, no wondering will it really fit and quality. You have someone local to bounce questions off if you run into a problem. They can give you tips as to what you may run into. Yes, they may be a little more $$$, but what is your peace of mind worth.
