Hey doc2002002, I am using Dolphin guages in my '48 and they too are to small so I used the original ss trim off of my orig. guages and bent the holding clamps backwards and then used the bracket that came w/ the Dolphin guages and whala.New guages filled the dash with the original trim ss ring. After I bought the guages and the EZ wiring package i was then to poor to pay attention :^)so I did what comes natural for me....make do with what you have. Good luck! Mike
