Ordered the Westin E-Series 23-2675 for my 4dr crew cab. Got them on Wednesday, but couldn't wait for the weekend to install them. So last night my son and I started the install.
The brackets are easy to put on, however we found that I had ordered the wrong bars. So I got on the phone with Amazon, they issued a RMA for the return. I ordered the correct Westin 23-2775 for my double/crew cab. The CS lady modified my order to give me 2 day shipping, and removed the shipping charges.
A+ to Amazon for their customer service. It may have been my fault for not paying attention, and I was greatful they worked with me to get me the right product.
