The person who I bought my 64 truck truck from was the third owner somewhere along the line some dummie cut a section out of the dash to install some guages. Might I add it was a hack job! This didn't stop me from Buying good deal I guess. I think that there was an ashtray maybe old radio if so lucky w/ options? The hole is 6 or 7 inches square. I don't need those options because truck is not going to be restored...mild custom. Can anyone give me some options. Fiberglass maybe?
