I had looked high and low for these with little or no luck finding them. I had found some that were close, but not like these. When I stumbled upon this website, I immediately searched for the "D" ring latches and low and behold they had them. The price was right and I had them in two days. Once I received them, I immediately went out and took the old ones off my topper and put these in their place. The bolt pattern was a little different, but using the top bolt hole as a starter, I install them and they worked perfectly. Now my back window on the camper is secure and no longer flops in the wind. I love them and would highly recommend them to anyone looking for some.
