These are leather hold downs that connect your bonnet to your rocker panel when you have a front flip nose. They come in black and tan and are essential to keeping a front flip bonnet from flying open.
Sold as a pair.
Installation note: When installing the lower piece of these straps, first drill the holes in the rocker. Then use sheet metal screws to secure the lower portion since you can't get inside the rocker to tighten. You may want to use some sort of sealant to prevent water from getting inside the rocker.
