Full set of 13x silicone sealing washers. These are the correct size and material to prevent water getting through the stud holes in the rain-rail (gutter). Fits Mazda MX5 and Roadster from 1989-2005 (may fit other soft-top cars)
If your rear-deck carpet is wet (under the back window) you may need to fit a set of these washers inside your rain-rail. Every hood-fit we undertake gets a set of these silicone washers, they have saved us hours and hours trouble.
