Maybe you can clarify what it is your are asking for?

I have seen trucks modified to use dashboards from other vehicles but that is fully custom. The one I particularly like is the 59-60 el camino dash shown in a recent Classic Trucks layout. The 57 Belair dash has also been used.

If this is what you are referring to then you are on your own as these were the work of the owners imagination and initiative.

If you are talking about the inserts for the gauges, those can be seen in any truck magazine.
