Review on 🔧 Premium Toyota Drain Plug Gaskets for Transfer Case - Set of 10 - Genuine OEM 90430-18008 by John Camelio

10 pack Bought from APSZone. A pack of 10 is much cheaper than buying it individually. Used these washers on a '92 Toyota pickup truck with a 5 speed manual transmission. Insert filler and drain plugs perfectly. I measured some washers with vernier calipers. The inner diameter is 18.20 inches. Once crushed, they fit snugly into the threads of the 18mm screw. The outside diameter varied but was usually around 24mm. The thickness was 2 mm.
