Fine.... I'l just keep hanging them with zip-ties and brackets all over the dash. It's just that I already have some that work fine and hate to spend the $ for nos or reproduction. I really needed an accurate temp gauge with numbers as I work out a cooling system for my project fridge. They just might fit through the original holes in the back panel that holds the speedometer. I held one up behind the finish face plate and you can read them through the original holes. It's not like I haven't already butchered most of the truck already. What's one more piece?
