guys, i'm building a custom guage cluster to go in the middle of my dash (theres holes from a jap tv there and i want to cover them) i have mech temp, oil and boost autometer guages. i want to leave my factory dash working i hear theres an extra hole for the oil pressure where american cars have their oil pressure (above filter) can this be used for an after market guage? would beat a t-piece on the old sender also.. is there a plugged hole in the water ways? id prefereably like one on the head whos done this before.. any experiences/things to look out for??
