Thats my question too. I've got the gauge cluster from my '46 1/2 ton Panel that I am not going to use. It has not been re-worked or anything but the panel itself is just surface rusted, I'm pretty sure I'm at work right now but I'll look in the morning. What I did with mine, since its not stock, is I made an insert for the gauges from a piece of oak with two trim pieces of cherry on both ends to match the curve of the dash.
