I need flame arrestors for my carter carbs the brass plate says 618S. I also need speedometer, I lost my orig to a fire when I sent it to be rebuilt. I would like black face white numbers 0-65MPH at least 3.75 inches wide. This is a boat I restored 17years ago, and bought it back July 2010 and it is almost done again from stem to stern and everything in between. Any information or help would be appreciated. Thanks.
