Well I got my twin gauge bezel in the plans of saving up for a JRSC, but I'm doing a few things to the Si and giving up until after it's paid off. Thus, now I have a boost and oil pressure gauge to still go into the car. Well I don't need the boost gauge so I'm selling it, what other kinds of usefull gauges could I look at getting once I sell the boost one? egt, voltmeter? Give me some other ideas. edit: they're autometer, btw. edit 2: They're 2 1/16" So I would need the same size.
