I agree that McMaster-Carr is the best! But the Car and Truck site in Orange, Ca. is pretty easy, if you click on the catalog that is for your particular truck/year. It shows pictures just like a paper catalog and is very reasonable on prices, and easy to find your part.
Also if you request, they will send you a paper catalog, that is just like the ones on the site.
