As part of the initial build on the 73 Cuda, I am buying and setting up an insert for those style gages. We did a template of a rally dash insert and will try and bend it out of aluminum from a drop at the recycle yard. Also want to 3D print an adapter to run the round led trailer lights on the back for a budget/rat build. If it works out we will upload the info to a site so others can use it in the future.
