Hi Everyone

I bought my g.f those aftermarket EL GAUGES for her 97 prelude, i've already installed a set for my car and i thought i would do hers as well, no biggy right?..wrong the damn thing didnt slot over the needles because it had an extra extension after the round bit if you know what im talking about anyway..i got frustrated so i remove the needles so they would fit ( i know i know im F**Kn stupid) i wasnt thinking straight and forgot that it would screw up the calibration.. now nothing works properly, RPM is dead, fuel is inaccurate, engine temp is dead, and the KM is ahead 10km... i know this thread will make ppl think what a dumb ass haha but i deserve it. All i want to know is where do i go to get this fixed? argghh!!

I live in sydney so any place in that area will do i just wanna fix it.
