I bought an aftermarket cargo cover and may have made a $140 mistake (https://www.amazon.com/dp/ (commissions earned) too late to return. I cannot get the metal bar into the second, lower hook as directed. It's easy to get it into the upper hook but not beyond. Per the instructions, using the upper hook makes it harder and noisier. Afraid if I get it in the lower hook, I won't be able to easily remove it. Is there a trick to this? If I have to eBay it, does the factor cover install and uninstall easily?
