I plan on installing a JVC radio/CD player in my 79. The in dash location was designed for a knob type radio. To put the JVC in this location would require cutting the dash to make it fit. I could save the cut-outs so if I wanted to bring it back to original configuration I could weld them back. The problem is there is no support behind the radio to support it when it is installed. I can fabricate a small box to weld in that location to support it, but I would rather find an install kit that would do the trick. The only one I can find only goes back to 1982. Any one have any suggestions or ideas or will the 1982 kit work? Thanks.
