Thank you for viewing. The item is an Inno roof carrier bar set. After purchase, I installed it, but it was a little short, so I bought a longer one. Therefore, it is almost unused, having only been installed on the actual vehicle once. Please check the manufacturer's website for details. I cannot answer questions about compatibility. The end caps will be attached and shipped. Shipping costs will be high due to the length. Please note that I cannot offer a discount. Please also check my self-introduction. Thank you for your consideration.
