Snap locations may vary depending on year and factory your hull was assembled. In this instance, there are male snaps/screws provided which can be added to the boat or you can use snap extenders.
These colors are not exact meaning they can vary slightly depending on the screen that you are using, the lighting that's hitting the cushions, and the background that you're comparing the color to. Therefore, please take these photo comparisons with a grain of salt. Cushions that have been on your boat will inherently have a different color due to sun exposure (ie: new cushions may be darker than originals based on age and exposure)
