I'm looking for a few specific replacement parts for my vehicle. First off, I need a right side mirror cover to replace the one that's damaged. Also, I'm in need of a back window wiper, as the current one isn't performing well. If you have these parts in stock or can source them for me, please provide the details regarding availability and pricing. In addition, if you could send over any information on the materials used and the warranty options available for these items, that would be great. I'm keen on ensuring that I get quality replacements, so any recommendations or alternative options you have would also be appreciated. Thanks!
