ok so today we went into the auto parts store to check out synthetics for my engine. while we were there we started discussing a-pillar gauges. first of all do they make an a-pillar piece that just replaces our factory piece with slots for 3 gauges? ive seen some that screw into the original a-pillar, but were going for the slick look. secondely how easy is an air/fuel ratio gauge to install??? and whats involed in this(where does it hook in to)? any other suggestions for places to mount gauges besides a-pillar? looking for answers, prayin for links/pictures. thanks guys!
