I have a 78 Blazer with the stock shaft style radio. I want to upgrade to a good aftermarket head unit, but I can't cut out a large enough space in the dash bezel to make it fit because of the design of the 78 bezel. I have noticed that some of the newer trucks have a different design for this area of the dash bezel that should be easy to cut out, but this bezel does not work with the 78 dash pad. I guess that I could try swapping the entire dash from a later model truck, but I like the look of the 78 dash pad. Does anyone have any suggestions?
