Hi. is it possible to put after market gauges it the stock instrument panel? If so, does anyone have any suggestions about brands of gauges and finding proper sizes to fit the stock holes? My panel just has dummy lights. I'd like to put a tach where the big dumb looking gas gauge is, leave the stock speedo where it is and fill the rest of the dummy light holes with mechanical amp, vacuum, gas and oil gauges. Any pics you guys might have of how you did yours would be appreciated too, if you have some. Thanks a lot!
