hey, looking to do a triple guage pod on my 2.4l ss cobalt on the flat part in the center of the dash.. will probly make it out of fibreglass.. just wondering what kinds of guages i should get.. i know i want a volt meter, oil pressure(electrical, not analog), but the third im stuck on.. maybe a/f ratio or oil temp.. what do you guys think? oh and what kind of guages have black faces with red needles so they will match the stock guages in my balt..
