You will find those at AutoZone..im sure the other big stores will have them as well, but I know AZ has them. And really cheap at that..well, REAL cheap in boating terms!
Ahh..sorry. We have them here at the AZ in Jacksonville. But we also have marine boat paint at our Lowes also.
After some research you want whats known as "Double End Christmas Tree clips", assuming one side is longer than the other..pic looks so. If both sides are even you want " Double ended nylon ribbed clips". I am finding them online but not in small quantities like you need. Maybe Fastenall or somewhere? I will look some more.
:::I found this site, I bet if you called them they WILL have what you need and sell in smaller numbers..like under 50..which I bet you want http://autobodyclips.com/index.php ::::
