Another parts fishing question, sorry. Hope this hasn’t been done to death in R World mags earlier.
My temp gauge cushion ring was just a hard black donut that crumbled to bits. They aren’t readily available of course. Are these cushions a similar PROFILE / cross section to the speedo and Tach cushions, just smaller diameter? I don’t have anything to reference to. My thought was to make one by cutting down one of the larger diameter cushion rings.
