Product is beautiful

Everything matched well. No instructions came with the tonneau top at all. We used youtube videos to help. As for customer service of this company: it was horrible. Ordered on July24th. Got it September 4th. We had to drive 115 miles to get it. Everytime I called they gave me different dates. I would not buy from them again. The product itself was good quality is about the only positive I can say.
