In the thread "Source for stainless steel engine vents Brian "Bridog" stated: Well ask and you shall receive. I was able to find the Imtra switch he posted here. I went through the process of figuring out how to make it of stainless. It will match that exact bolt pattern, but won't have the small detent on the lip. The weight alone will hold the lid down. It will also have a real hinge, not a hooked in one like the originals. These should be as easy as unscrewing the plastic one and screwing these back down. I will have pricing tomorrow, but it will be determined, just like the vents on how many are ordered.
