Last week, I obtained a triple gauge bezel assembly through an ebay seller. The plan is to move the radio down and install gauges in the radio's original location. Question is: How do the gauges attach to the bezel assembly? The bezel assembly doesn't have any clamping fixtures with it. Should there be some to attach to the plastic assembly? The triple gauge bezel that I have probably came from a mid 80s turbo. I'm planning on installing it into my 93.

A related question: From ebay, I also found a flat plate adapter to move the radio from top center to the bottom center dash location where currently there is a catch-all tray. The plate adapter seems to be for the older style radios with small dial and a knob on each side of it. If you know which plate I'm describing, can this plate be modified to use with the original 93 radio which only has one knob on left and the rest button controls? There is a rectangular outline molded into the plate. Should the plastic material inside of this rectangle be cut out for the later style of radios?

Thanks in advance for any tips and pointers.
